"ZZ Blues" is a song from Sesame Street, sung by a look-alike Muppet band of ZZ Top, here called "Over the Top". The song tells about the letter "Z", and how there are not enough words starting with the letter. By the end of the song, the band (including the lead singer, who "cops some Z's himself") fall asleep from singing about the letter Z, and finish the song as they snooze away.
