"Wembley, Wembley, Number 9" is sung by the Fraggles (and a few Doozers) after Wembley accidentally spills love potion in the Fraggle Pond, causing everyone who inhales it to fall madly in love with him. The song is performed in the Fraggle Rock episode "We Love You, Wembley."

The tune and lyrics are a retread of the song "Lover, Lover, Number 9," which was sung earlier in the episode.
