A decade since radio rock band Train’s last Top 10 hit, nine years since its last charting album, with singer Pat Monahan its only original member, it seemed fair that the band would offer a show focused on its past when it headlined Musikfest’s main Wind Creek Steel Stage Aug. 3.

With its hits now dating back more than 28 years and 20 Top 20 songs, 15 of them gold and platinum, with sales totaling nearly 50 million copies, Train certainly has the material to make that a successful show.

And Train did just that in a 20-song, one hour-and-28-minute concert, except for two prominent exceptions (more about that later).

The surprise was just how well those songs were performed, and how entertaining and fun the night was.

It started strongly, and appropriately, with “She’s on Fire,” the opening track from Train’s sophomore album, “Drops of Jupiter,” celebrating its 25th anniversary this year. The song, a minor hit, was forceful and rocking, as if the band wanted to serve notice of its level of talent.

That was followed by 2013’s triple-platinum “50 Ways to Say Goodbye,” on which the now-five-man Train not only recreated the level of the recorded version, but added a live vibe that elevated the song.

Monahan showed on the 2010 platinum hit “If It’s Love” that his voice, while older, remains sharp and strong.

“Bethlehem, are you with me so far?” he asked the near-sellout crown, which responded hardily, as it did all night.

Monahan later noted it was the band’s sixth time headlining Musikfest, and the audience response showed why. He also made a local connection, saying the band on Aug. 2 had dinner at Allentown’s Union and Finch restaurant.

Throughout the show, Train offered a few deeper cuts: the 2022 minor hit “AM Gold,” the 2014 gold hit “Angel in Blue Jeans” and “Mississippi,” which Monahan, an Erie native, called “maybe my favorite song from the ‘Drops of Jupiter’ album,” but said, “I’d rather have Pennsylvania anyway.”

That song was saved, and lengthened, by a solo from guitarist Butch Walker.

The band even offered up a cover of John Mellencamp’s “Jack and Diane,” on which Walker shared vocals. While it wasn’t as good as the original, it fit the vibe of the show, especially when Monahan enlisted the crowd to sing the chorus.

This was among several formulaic concert tricks Train used. There were two confetti blasts, there were five huge beach balls released into the crowd, and there was an audience singing contest on the 2011 gold “Save Me San Francisco.”

But all of it seemed fun, and none of it forced or intrusive.

There was another audience chorus sing-along on the excellent 2003 platinum chart-topper “Calling All Angels,” but that song’s bigger impact was to prove how Train’s hits made the show.

The 2016 triple-platinum “Play That Song,” offered early, in addition to being well-played was light, fun and nostalgic, with Monahan in a fun mood.

A nine-minute version of the band’s breakthrough hit, 1998’s “Meet Virginia” (“Any of you old enough to remember this one?” Monahan asked), while not as caustic as the original, was a crowd favorite, and added a long guitar solo as Monahan threw “Meet Virginia” T-shirts to the crowd (he has a pretty good arm!), including one that the entire band signed during the song.

They ended the song with a two-minute snippet of Steve Miller’s “The Joker,” which seemed fitting.

Later in the concert, even better was the 2012 platinum “Bruises,” which tells the tale of carrying life’s scars, which also was appropriate for the night and very touching. Bassist Hector Maldonado, who has been with the band 17 years, sang country singer Ashley Monroe’s part from the recorded version.

The best of the night was the mid-concert offering of 2010’s four-times-platinum “Marry Me,” which Monahan sang alone on acoustic guitar in a spotlight. His investedness and intensity were obvious, and he even sang the last chorus a cappella.

After that song, Monahan told the crowd, “This is where we reboot,” and brought out his 14-year-old son, Rock, who sang and played lead guitar on a really good cover of Journey’s “Stone in Love” as Monahan moved to drums.

His son sang very well, and really shredded on guitar. He stayed to play on “Save Me San Francisco.”

If this was an indication of the future of the Monahan lineage, the night’s other offering that looked forward was the band’s new single, “Pennsylvania Turnpike.” A new album, “Mad Dog in the Fog,” is due out Aug. 28.

The song fits the Train catalog well, an emotional and nostalgic recounting of Monahan’s trip from Erie to California to form Train (it doesn’t mention the Northeast Extension).

Slow and soaring, it looks to the future by recounting that very past that has made Train as successful as it is today.

Train wound down the show with its biggest hit, 2009’s 13-times-platinum “Hey, Soul Sister,” sending a ripple of excitement through the crowd with the opening notes. It, too, was very well performed.

After a superfluous cover of Dirty Head’s “Vacation,” Train played its six-times-platinum 2001 chart-topper “Drive By,” with Monahan still in good voice that late in the show.

Then a minute-long version of The Beatles’ “Hey Jude,” with the crowd again singing along, before closing with a six-minute version of the 10-times-platinum title track from “Drops of Jupiter.”

There was no encore, but one was hardly needed. The audience sang the entire “Na na na na na” chorus,” and Monahan told them, “You sound amazing. Thank you, Pennsylvania. Think we could come back next time?”

There’s no reason for Train to stop its journey, and Musikfest seems like an obvious destination.

Opening act George Pippen, who has had success as an acoustic Americana performer on Tik Tok, opened the night with an 11-song, 45-minute set.

His start was very strong, raspy voice and harmonica, backed by a guitarist and drummer, on “Ain’t My Home Yet.” His second song, “I-65,” the type of reflective song that made Train’s set so successful, also was very good.

The rest of his set offered little different, even his cover of the much-covered Tyler Childers song “Jersey Giant,” or his new single, “Roanoke.”

With a slightly broadened spectrum, Pippen could be a voice to watch.
