Katy Perry's 'Last Friday Night' Invite Thrills Hanson 'We thought we could bring the party — even if it was a fictional party,' Taylor Hanson tells MTV News of video cameo.

Katy Perry rounded up quite the cast of cameos for her "Last Friday Night" video. The Marc Klasfeld-directed clip featured "Glee" stars Darren Criss and Kevin McHale, "Friday" singer Rebecca Black, Kenny G, Debbie Gibson and Corey Feldman. Oh, yeah: It also had Hanson as the video's house band!

"We were flattered to be asked, and it was great to be a part of it," Taylor Hanson told MTV News on Tuesday (June 14). "We had a really good time. It was one of those things that worked out really well. They said [they] needed a band to play the party, and we thought we could bring the party — even if it was a fictional party. 

"First of all, Kenny G's an icon, so it was pretty awesome to, in some ways, have been able to perform together," Taylor continued. "And, again, there's a little bit of the tongue-in-cheek element to the entire concept of the video. We went in there without taking it too seriously. [Kenny G] was a scholar and gentleman, and it seemed like Katy was fulfilling the idea. She seemed like she was pretty happy with how things were coming together."

Taylor said it was hard to get Perry out of character as the geeky Kathy Beth Terry on set. "She was completely in character and to the point of like, 'OK, where does Katy Perry begin and this character end?' " he recalled. "And, honestly, it seemed like she kind of is a Method person. She seems like she goes in all the way. So we hung out a little bit, and during the performance and everything, obviously, we were all there on set, but she was definitely inside of the character throughout the shoot, which sounds tiring to me."

So what would it take to get the guys to play your house party? "We work for Twizzlers and good times," Taylor said. "You'd have to have a lot of spandex, a huge tree covered in toilet paper, Kenny G — apparently that's what it takes to get us to a house party."

And now Katy owes the brothers a cameo in their next video. "I think she has some obligation to spread the love on the next round," he said. "I don't know. ... We might have to come up with another character."
