Here's a lighthearted, fun song for your next graduation or moving on ceremony. Since the song is set in a mock '50s rock style, you can let your singers ham it up a bit with effected singing. If you use the song in performance, consider letting them dress in costumes from the era as well.
The first time through the song, the singers are in unison. After the bridge, there are two parts. Part 2 is optional, but since it's just an echo of part 1, you will find it easy to include. (from Music K-8, Vol. 9, No. 5)
