A friend recently turned me on to a cover band called "The Dead Hensons". They cover Jim Henson tunes, mostly from the Muppets and Sesame Street. Very cool. Brings back lots of memories. They used to have more free tracks on their website - including Rainbow Connection, Ladybug Picnic, and Mahna Mahna. I'll scour the web a little harder and see if those are still available anywhere, as those were their best tracks. Check out the link - The Dead Hensons!
