I can only think of 3 occasions where you can hear his then raspy, smoky voice in some classic sketches: 1. "Me Claudius" from Monsterpiece Theater 2. The song "We are all Monsters"- the original, I say original because the DVD "Monster Hits" has Elmo singing with his present squeaky voice. 3. There was once a sketch featuring Betty Lou (?) with some monsters in a parade going opposite directions; the most irritating part in that clip was hearing Betty saying:" Wait a minute, wait a minute,wait a munite". But those were the days nevertheless.
