Recorded a version of "You're The One That I Want" from 'Grease' with Arthur Mullard. The song with comically altered text as if the words had been slightly misheard (a trade mark for Hylda) such as "if you're chilled with infection, you're too sly to convey" made number 22 in the British charts in 1978. This earned the pair an appearance on BBC TV's Top of the Pops.
