Roy Clark sang his 1969 hit, "Yesterday When I Was Young" on episode 303 of The Muppet Show.

Muppy appears in the number first as a live dog in wide shots, before being replaced by the puppet in close-ups.

The song was originally titled "Hier Encore" in French, and was written and recorded by first season guest star Charles Aznavour.
