Can anyone think of a song that we could sing together... it doesn't have to be written as a duet as we can get it arranged for 2 people. It just has to be "graduation-y". The first thing that popped into my head was "Theres Gotta Be SOmething Better Than This" from Sweet Charity but I think the administration would frown upon that.
Also.. it doesn't neccessarily have to be from a musical and it could be funny or sappy. Either is fine.
If you can't think of something that could be a duet... what about 2 solos?
