O-Town's Tour Demands Are All '90s Or Nothing

O-Town's either stuck in the '90s or they just have a great sense of humor about their upcoming tour.

The boy band's hitting the road with 98 Degrees, Dream and Ryan Cabrera for the nostalgic MY2K Tour and their rider is filled with throwback items like a '90s boombox "to play their sweet cassette collection" ... and a Nintendo 64 to "play GoldenEye."

Other backstage demands include cases of local beer, assorted liquors, 5 cans of silly string and a back scratcher.

Most bizarre on their list is definitely the kitty litter and wet cat food "for the stray cats the band takes in while on the road."

That's gotta be code.
