The song is sung by a male but I only know the chorus. I heard it while shopping at Acme but when I asked, the people said it wasn't radio playing but tape so they couldn't help me. I don't know much but what I do know might be enough. I couldn't hear any lyrics but the chorus is sung by a guy with a high pitched voice (falsetto I think) and all he says is:
Ooo Ah oooo OooooOoo
F-D G-D#-D F-D-C-D#-C-B(flat)-A-B(flat)
It's done 4 times and the last OooooOoo is done really fast (if youre actually trying to play it on piano). His voice is really high. The song is very upbeat and happy. I wish this site had a record feature so that i could just sing it. Anyone who knows the song would know the tune. It's basically most of the song.
