Sandy Bradley and the Small Wonder String Band (a/k/a Greg and Jere Canote) recorded one with a chorus that goes:

Makes me feel like the good old days
Happy Birthday to you!
Sure grew out of your baby ways
Happy Birthday to you!
____ birthday, we wish you many more
Health and wealth and friends by the score
So cut the cake and let's eat some more
Happy Birthday to you!

That one's pretty agreeable...I'm sorry I don't remember the name of the author. Each verse is about a different birthday in a person's life when he wasn't feeling particularly cared for, and then there was a surprise party and "His friends jumped up and they hollered real hard, 'Happy Birthday to you!'"

Aloha,
Mark
