One of the best birthday songs is called Cut the Cake and is sung by John McCutcheon. (not the song asked for, but one verse is about
how the birthday person is so busy at work they forget it is their b-day)

When the birthday person get home they are
"taken off guard, with chairs and tables all over the yard,
and their friends jump up and holler real hard..."
