I just found out that Jefferson Airplane DID NOT play the music on the Jazzy Spies cartoons from the early days of Sesame Street. I had always thought that, since vocalist Grace Slick was with JA at the time. I found a Muppet Wiki link stating the real names of the Jazzy Spies musicians:

Also, I will throw my hat into the "mispronouncing Dave Goelz's name" ring. As a kid, I said Go-Lez

!

. For years, I was kind of

about how to say his name, and now that I look back, it wasn't very

on my behalf.
