Willis Edward Hall was an English playwright and radio, television and film writer who drew on his working-class roots in Leeds for much of his writing. Willis formed an extremely prolific partnership with his life-long friend Keith Waterhouse producing over 250 works. He wrote plays such as Billy Liar, The Long and the Short and the Tall, and Celebration; the screenplays for Whistle Down the Wind, A Kind of Loving and Alfred Hitchcock's Torn Curtain; and television programmes including Budgie, Worzel Gummidge and Minder. His passion for musical theatre led to a string of hits, including Wind in the Willows, The Card, and George Stiles' and Anthony Drewe's Peter Pan: A Musical Adventure.

Billy Liar is a 1959 novel by Keith Waterhouse that was later adapted into a play, a film, a musical and a TV series. The work has inspired and been featured in a number of popular songs.
