George Thorogood has been on the “Baddest Show on Earth” tour since 2024.

It began as a celebration of being on the road for 50 years. He and his band, the Destroyers, have sold more than 15 million records.

For a man who has opened for the Rolling Stones and played “Live Aid” with Bo Diddley and Albert Collins, Thorogood does not seem to take himself too seriously.

During a phone interview, Thorogood, 77 (born Feb. 24, 1950), jokes that he thought this tour might have begun in 1924, and that the tour ends when he gets exhausted.

Thorogood has 17 concerts booked in May alone, including at 8 p.m. May 3, Penn’s Peak, Jim Thorpe.

It’s his fourth concert at The Peak.

His other Lehigh Valley concerts include Musikfest, Bethlehem, in 2013, 2009 and 2005; Wind Creek Event Center, Bethlehem, in 2023; Miller Symphony Hall, Allentown, in 2015, and Stabler Arena, Bethlehem, in 1988.

Thorogood’s many hits include covers of songs that were somewhat obscure before he recorded them, such as Elmore James’ “Madison Blues,” released by Thorogood in 1977, and Amos Milburn’s “One Bourbon, One Scotch, One Beer,” later adapted by John Lee Hooker, and released by Thorogood in 1977.

The Wilmington, Del., native says that finding songs like that would be impossible today. “Nothing is obscure anymore. Everything is exposed in this day and age,” Thorogood says in a phone interview from his home in California.

Thorogood covered the well-known “Who Do You Love” by Bo Diddley, released by Thorogood in 1978, and “Move It on Over” by Hank Williams, released by Thorogood in 1978.

Thorogood’s 2022 album, “The Original George Thorogood,” features his self-penned songs, including “I Drink Alone,” originally released by Thorogood in 1985, and the song most associated with him, “Bad to the Bone,” originally released by Thorogood in 1982.

Thorogood plays and sings as hard as he ever did. He claims he will retire if he ever loses his edge:

“We want to go out while we are still on top, until I can’t take it any further, and as long as the audience stays young.”

He does not want to dilute his show:

“If you take the best bourbon in the world, add a little water, then add a little more, it gets so nothing is left. I don’t want people to say, ‘You should have seen them ten years ago,’ although it might be OK if they said, ‘You should have seen them six weeks ago.’

“The New York Yankees did not want Joe DiMaggio to retire. They told him, ‘Your numbers are still good.’ He said, ‘Yeah, but they are not DiMaggio numbers.’ I respect that.”

Thorogood is known for his slide guitar work, inspired by the blues artists he saw when he started:

“Everybody I saw played slide. I thought I was supposed to.”

His bandmates in the Destroyers are: Jim Suhler, guitar; Buddy Leach, saxophone; Billy Blough, bass, and Jeff Simon, drums.

Simon is an original member of the band. Blough has been a band member since the 1970s.

Thorogood is scheduled to release a live album this year, which would be his 32nd release, according to his website.

“It is done. We just have to do the other parts to get it ready for release.” He does not want to say anything else about the album, except that “It’s the greatest thing that ever happened.”

Since nearly all of the original blues artists are gone, Thorogood thinks what he does now is an interpretation of the blues:

“I was three feet away from Muddy Waters when he was playing a Robert Johnson song. You can’t do better than that.”

As far as younger players hearing the blues and carrying on the tradition, he says, “Anything that is good will get through to somebody if they are supposed to find it.”
