Don't be afraid to toss a fake limb or two on stage tonight at the Crowbar -- Reel Big Fish (RBF) will be more than ready for it.

Aaron Barrett, RBF's lead singer and guitarist, said his band, along with The Tossers and Transition, will be prepared for anything -- especially after RBF's recently finished tour, where Barrett described a few stories that were nothing short of hilarious.

"When we were in Australia, this guy threw his prosthetic leg up on stage," Barrett said. "We gave it back to him eventually."

These days, the band that made its notoriously catchy hits "Beer" and "Sell Out" ingrained in the minds of ska-lovers everywhere is promoting its newest album, We're Not Happy 'Til You're Not Happy. Barrett said that while the ska genre is not the popular scene it was in the late 90s, he and his band are happier than ever to still be contributing.

"I'm not embarrassed about the word ska. I'm proud to be part of it," Barrett said. "I'd say we're a ska band, [but] we do play lots of different kinds of music."

As goofy as the band still is, Barrett said the mindset of live performances has matured since it began more than 10 years ago.

"It used to be how funny we were [on stage] and how bad we played, but now we're into our musicianship. Not that anyone will notice any difference," Barrett said jokingly. "We're just trying to be a good band."

Joining the Fish on tour is Chicago-based folk-punk band The Tossers. Creating its unique sound with instruments that include a mandolin, a fiddle and a tin whistle, it's hard to imagine frenetic punkers moshing to such music -- but the seven-piece band is out to prove that they can be as energetic as any combination of electric guitars.

"We're kind of like our own entity," Tossers vocalist and mandolin player Tony "T." Duggins said. "We draw influences from tons of other people. There's a bit of a scene for what we play ... we're kind of in between rock 'n' roll and folk music."

Because of the band's unusual variety of instruments, Duggins said sometimes just having good sound in the venue they play makes them happy about the show they're playing.

"It's hard to mic our instruments, so if we sound good, then we're happy," Duggins said. "And if people are having fun and are into it, then I guess we consider that a pretty decent show ... also if nobody is trying to fight us," he added, laughing.

The youngest of the three bands on the tour, Transition, a band that calls Pittsburgh home, is playing the role of "up-and-comer" the best that it can, as vocalist Dan Smyers said he's excited to be part of a tour with RBF.

"We're looking forward to playing some bigger venues than we're used to," Smyers said.

Smyers said the band, which cites Jimmy Eat World and Saves the Day as its influences, is working on a full-length album that should hit stores in the spring. The band's also working with MxPx front man Mike Herrera, who is producing the album.

"We all have a lot of friends at Penn State ... we're playing a lot of new songs we've never played before, so we're just hoping for a good response," Smyers said.
