Dr. Teeth and The Electric Mayhem firmly established as the regular Muppet pianist. Later performances mostly feature lead vocals by Floyd or Janice and only a few featured Dr. Teeth. His speaking roles got even smaller after his performer Jim Henson's death; an exception was the 1991 Muppets stage show "Muppets on Location: Days of Swine and Roses", the voice being performed by John Kennedy.

Dr. Hook & the Medicine Show Shel Silverstein. The band had eight years of regular chart hits, in both the United States, where their music was played on top-40, easy listening, and country music outlets, and throughout the English-speaking world including the UK, Canada and South Africa. Their music spanned several genres, mostly novelty songs and acoustic ballads in their early years; their greatest success came with their later material, mostly consisting of disco-influenced soft rock, which the band recorded under the shortened name "Dr. Hook". Dr Hook recently announced that they will be celebrating their 50th Anniversary with the Dr. Hook 50th Anniversary World Tour
