Stan Kelly-Bootle, English singer-songwriter, computer scientist, and author (d. 2014)
Stanley Bootle, known as Stan Kelly-Bootle (15 September 1929 – 16 April 2014), was a British author, academic, singer-songwriter and computer scientist.

He took his stage name Stan Kelly (he was not known as Stan Kelly-Bootle in folk music circles) from the Irish folk song "Kelly, the boy from Killane". His best-known song is the "Liverpool Lullaby" or "The Mucky Kid" which was recorded in 1965 on the Three City Four LP and sung by Marian McKenzie. It was also sung by the Ian Campbell Folk Group on the Contemporary Campbells LP. It was later recorded by Judy Collins in 1966 for her album In My Life. Cilla Black recorded it three years later as the B-side to her pop hit "Conversations". Kelly-Bootle achieved the first postgraduate degree in computer science in 1954, from the University of Cambridge.
