Leslie Uggams and Big Bird sing "Love Will Keep Us Together" for the closing number in episode 318 of The Muppet Show.

The song was originally recorded by one of its writers, Neil Sedaka, but not released as a single. In 1975 it was covered by Captain and Tenille who had their first number one hit with it.

During the audition process for the casting of Walter for The Muppets, Peter Linz and Jason Segel performed the song together.^[1]
