What song is this??

[neamhni]

Just saw Sesame Street Live: Can't Stop Singing and in the middle, Elmo sings a counting song "1,2,3,4,5" and he's conducting different types of music to the same tune. The tune is a recognizable opera tune but I can't figure out what it is! I've googled it to no avail. Can anyone help me with this??

Thanks in advance!

Sorry! I've never heard it. Now, if someone can upload the video on YouTube, I may recognize it.

It's "Caro nome" from Rigoletto.
