In a coda to her musical career, she teamed with Arthur Mullard in 1978 to record a comedy version of "You're the One That I Want" from the film "Grease". Baker and Mullard, then aged 73 and 68, dressed in wigs and costumes similar to the John Travolta and Olivia Newton-John characters from "Grease" and appeared on the BBC show "Top of the Pops" and the Granada Television music show for children "Get It Together". Their version reached #22 in the UK’s BBC singles chart. The two entertainers recorded an album of pop covers entitled "Band on the Trot".
