As I was saying, here is a list of the changes made to the Zoot endings...
Kaye Ballard - for this episode Rowlf is forced to play the end theme by himself following the departure of the house band (*not* the Electric Mayhem). The original ending, which is missing from the DVD, shows Rowlf looking nervously at the camera while Nigel bows to the audience.
Loretta Lynn - the final shot is meant to be of the house band at the railroad station. Again, this is missing from the DVD.
Harry Belafonte - the final note is played onstage by one of the African-masked puppets. From memory, it's the one performed by Jerry Nelson.
Roger Miller - chicken-Zoot plays the final note. Later syndicated versions removed the original final shots of the orchestra pit and Zoot playing the final note; these are missing from the DVD.
Dudley Moore - When Animal hits MAMA, it plays the final note and then Animal falls to the ground as though he has been electrocuted.
Mac Davis - the final note is played by one of the Beakers. As with the Roger Miller episode, later versions edited out the final shots of the orchestra pit and Beaker playing the final note.
Whew! Any questions?
