"Ring-A-Ding Ding!"

It's Deana Martin on the line.

When you hear Deana Martin duet with her father, Dean Martin, in her "Tribute to Frank Sinatra and Dean Martin" concert, 8 p.m. April 25, State Theatre for the Arts, Easton, you'll be amazed at how beautifully their voices blend.

Deana Martin, just like her dad, is a natural.

At the State Theatre, Deana will sing "True Love" accompanied by a quintet with her father's voice on the original track.

That's just one pop classic sure to "Wow" Lehigh Valley audiences in a concert of pop standards, anecdotes and video clips.

Deana herself was wowed when she recorded the "True Love" duet for "Destination Moon," her fourth and latest CD of standards from the American Songbook. Dean Martin's recording of Cole Porter's "True Love" was first released on his album, "This Time I'm Swingin'" (1960).

For the "True Love" duet, Deana returned to the very studio at Capitol Records, Hollywood, where her father Dean recorded such swinging hits as "Ain't That a Kick in the Head," "You're Nobody 'Till Somebody Loves You," "Memories Are Made of This" and "Everybody Loves Somebody."

"Just walking down the hallway to Studio A ... photographs line the wall. It's dad and Bobby Darin and ... It makes you feel incredible. It's an amazing feeling just being there," Deana Martin recalls in a recent phone interview from Branson, Mo., where she and her husband, John Griffeth, who produced "Destination Moon," have a home.

Engineer for the Deana-Dean "True Love" duet was 19-time Grammy winner Al Schmitt, who worked his magic for the duet Natalie Cole did with her late father, Nat King Cole, on "Unforgettable" for her 1991 album, and was engineer on Frank Sinatra's "Duets" albums.

At the iconic round "stack-of-wax" Capitol building, Deana's husband found the hand-written Nelson Riddle arrangement for her father's recording of "True Love."

"I was holding the original chart that my dad used. It had 'Dean' written up in the corner. Hearing his voice through my headphones, I couldn't even sing. I felt him there with me."

"True Love," with playful pumping baritone sax, jaunty muted trumpets and lush strings, echoes Deana's sentiments. "For you and I have a guardian angel," Dean sings. Deana sings back, "On high, with nothin' ... nothin' to do."

Deana's voice is crystalline and expressive, tender yet strong, with a casualness reminiscent of her dad's, as she glides across the notes.

Throughout "Destination Moon," Deana has a wink-wink in her voice. After all, in the photo on the CD cover, she's in jewels, black strapless dress, a pair of black stilettos dangling in one hand.

"Ring-A-Ding Ding!"

Deana Martin is on the road about 280 days of the year. She's booked through 2015. "It's a lot of shows. We get there a day ahead and I do TV interviews, then rehearsals and the show.

"Every time I go into the recording studio and go up on stage, it's exciting. That's what every performer is hoping for to touch the audience."

Following her show at the State Theatre, she departs the next day for a concert at the Strand Theatre, York.

"But it's all worth it," she says. "To get up there and sing this wonderful music. And to bring memories back and to make new ones."

Deana Martin grew up in a household and lifestyle in Los Angeles, where she and her husband also have a residence, surrounded by celebrities and song.

"I was listening to other singers: Uncle Frank Sinatra, and Uncle Sammy [Davis, Jr.], Bobby Darin, Rosemary Clooney, Peggy Lee and Ella Fitzgerald. Their music was playing in our home.

"I could tell who it was seconds after I listened to them singing. Same with my dad you could tell it was my dad the second he opened his mouth."

Imagine getting vocal and performing tips from none other than Ole Blue Eyes.

"He taught me phrasing," she says of Sinatra.

"He recorded his songs many times because [he told me], 'The songs would change meaning as I got older. And on the road.' He [Sinatra] said, 'You may sing it differently every time you go on stage.'

"My dad had this laid-back natural style. He was the 'King of Cool.' And he made everything look easy. And it's not that easy," Deana says.

In 2009, Dean Martin was honored with a posthumous Grammy Lifetime Achievement Award.

Dean Martin (1917 - 1995) was one of the legendary "Rat Pack" of Frank Sinatra, Sammy Davis, Jr., Peter Lawford and Joey Bishop, who first appeared together in the movie, "Ocean's 11" (1960). The media tag originally described a group that gathered at the Hollywood home of Humphrey Bogart and Lauren Bacall.

"Ring-A-Ding Ding!," title song of a 1961 Sinatra album, became a catch phrase during the Rat Pack's Las Vegas casino concerts and entered the swinger lexicon.

If her dad is the "King of Cool," a title Elvis Presley is said to have bestowed on Dean Martin, then Deana Martin is the "Countess of Cool."

Deana Martin appeared on her father's TV show, "The Dean Martin Show" (1965 - 1974); has done movies, hosts a satellite radio show, and wrote an autobiography, "Memories Are Made of This." She expects to autograph her book and CDs after her concert at the State, where they'll be available for purchase.

At a young age, Deana got acting encouragement from none other than Judy Garland.

"I was at her [Garland's] house on [South] Mapleton [Drive, Holmby Hills, Calif.] to play with Liza, Lorna and Joey. I know it's just like out of a movie: 'Let's put on a play.' I was a tree. She [Garland] leaned down and said, 'Deana, you were the best tree I've ever seen.' So, she was my first critic."

Deana says her father's movie acting career was underappreciated.

"He [Dean Martin] probably should have been nominated for 'Rio Bravo' [with John Wayne, 1959] Also, he was amazing in 'Some Came Running' [with Frank Sinatra, 1958] and 'The Young Lions' [with Marlon Brando, Montgomery Clift, 1958]."

If technology brings Deana and Dean Martin together again on stage and CD, Deana marvels at the contemporary pop music scene.

"There can be a little boy or little girl in their bedroom, playing their guitar, and they hit iTunes and they become an instant hit all over the world.

"When I was growing up, you had to knock on doors, or play the Troubadour [West Hollywood] on Monday night."

Deana says the songs she sings and records have a quality that spans the generations: "They're classic timeless songs."

She recalls a concert in Beverly Hills:

"We had 60-year-olds sitting next to twenty-somethings. And they were all beautifully-dressed. They were cool.

"It's amazing to me that it's coming into new generations. Keeping this fabulous music alive I couldn't be happier."
