Elmo's World theme song history (in honor of Elmo's birthday)

I know Elmo's birthday, but this video didn't come to mind originally at the time. Also, I grew up with the original Elmo's World, and it seems as if this segment has had many different intros since it was introduced on Sesame Street in 1998.
