Scooter and some frogs (briefly) sing "At the Hop" in episode 222 of The Muppet Show.

Scooter sings the melody and the frogs sing backup until they get to the part, "Let's go to the hop..." The frogs then stop and beg to go to the hop. Scooter attempts to calm them and encourage them to sing the rest, but he fails and says, "Never mind" and hops offstage with the frogs.

The song was a #1 hit for Danny & the Juniors in 1957.
