"Famous" was followed by their TV show theme "Big Time Rush" and then "Til I Forget About You." The audience loved it and showed how much by singing along, clapping to the beat and waving handmade signs declaring love for the group's four members -- Kendall, Logan, Carlos and James.
They kept the crowd of mostly teenagers, their younger siblings and parents focused on them with vocals that were tighter than their sometimes stilted dance moves.
The group performed songs from their album, as well as singles that came before its release, including "Nothing Even Matters" and "Any Kind of Guy."
The four-man band worked through nine songs, all the while making it look like hyping an audience that didn't come to see you is easy.
The group saved their infectious radio hit "Tonight Tonight" for last, but frontman RK Follese had concert-goers eating out of his hand long before the 45-minute set was over.
Follese proved that he's got pipes during the band's only cover of the night, Katy Perry's "Teenage" Dream," and got folks dancing, clapping and singing along with original material.
Follese said "I Like It Like That," a laid-back party song similar to "Tonight Tonight," and several other tunes would appear on Hot Chelle Rae's album set for release this fall.
Big Time Rush released their debut album, "B.T.R", in 2010. It includes the single "Boyfriend," which features a few family-friendly verses from Snoop Dogg and received modest radio play earlier this year, peaking at No. 72 on Billboard's Hot 100.
Sadly, Snoop, whose herb-laced April performance at Allentown's Croc Rock was anything but wholesome, didn't show up to tack a 13 onto the concert's PG rating.
Fair-goers didn't seem to mind, though. Neither did the band. They performed the head-nodder with zest.
In a nod to their squeaky-clean image, Big Time Rush asked, "How many parents are in the audience?" during a break for three acoustic songs. They dedicated their next tune, a cover of The Beatles "I Want to Hold Your Hand," to mom and dad.
Next up, BTR pulled a willing, but overwhelmed teenage girl on stage and flanked her as they sang "Worldwide," a slow number about missing that special someone, presumably while one is on tour.
The group began the acoustic set with the ballad "Stuck," proving they can harmonize outside the studio and needn't rely on a backing track.
On the Nickelodeon series that shares their band's name, Kendall Schmidt, James Maslow, Carlos Pena Jr. and Logan Henderson portray a group of teenage hockey players from Minnesota whose skills off the ice score them a chance to shine on stage in Hollywood.
Off TV, Kendall is a 20-year-old Kansas native, James, 21, is a Californian with New York City roots, Carlos is a 22-year-old Missourian raised in Florida and Logan, 21, is a born and bred Texan.
The show, which has been renewed for a third season, catapulted the acting, singing and dancing foursome to stardom -- at least in the realm inhabited by teens and tweens. Big Time Rush earned Favorite TV Show and Favorite Music Group nominations at this year's Kids Choice Awards.
Fellow Nickelodeon star Miranda Cosgrove, who performed last month at Musikfest, beat out BTR in the "Favorite TV Show" category. She stars in "iCarly."
BTR, of course, reminded fans about the new season during the show. They also mentioned -- over raucous screams -- that another album is on the way in November and a movie starring "Big Time Rush" is in the works.
