Katy Perry was the musical guest last night on Saturday Night Live. She entertained the crowd by performing "Roar" and "Walking On Air." Both songs were matched with the appropriate costumes. "Roar" had Perry dressed in jungle-themed garb, with the backup vocalists and band all dressed as animals that would appear in the jungle. For "Walking On Air," Perry wore a white top and a plaid skirt, and was accompanied by backup dancers who attempted to mimic wind motions.

"Roar" and "Walking On Air" are the first two singles off Perry's upcoming album, Prism. The album, which only has a guest appearance from Juicy J, is coming out in two days.
