Upbeat duet selection: EASY TEN!!?

My friend and I are performing at a showcase and then we were thrown a loop: We have to do a duet. We're both soloists. But we both work fast and we're best friends so it's okay! Problem is the showcase is next week and we have no music!!!!! We are looking for an upbeat song that would be okay to sing at a high school showcase, something that isn't necessarily about love, and nothing sad!!! It's a fundraiser and it would preferably be easy to learn. We're both alto/sopranos so we can sing either part. Oh yeah, we're both girls! Maybe not something that's super mainstream all over the radio right this minute? Please help this is a huge event we were asked to do and it could make or break our status with the coordinators! EASY TEN POINTS!!!!!! ESPECIALLY IF YOU ATTACH THE MUSIC :) thanks!
