Gallagher and Lyle were a Scottish musical duo, comprising singer-songwriters Bernard Joseph "Benny" Gallagher (born 10 June 1945, Largs, Ayrshire) and Graham Hamilton Lyle (born 11 March 1944, Bellshill, Lanarkshire).
Their first recognition came in 1968, when they were signed by The Beatles to write for Apple Records’ artists. They were founding members of the band McGuinness Flint and wrote the 1970 UK chart hit "When I'm Dead and Gone". They formed the duo Gallagher and Lyle in 1972 and their fifth album Breakaway charted and included the hit songs "Heart on My Sleeve" and "I Wanna Stay with You." Don Williams took their song "Stay Young" to No. 1 on US Country charts. The duo split in 1979. Gallagher and Lyle have worked, jointly and individually, on records with, among others, Paul McCartney, Eric Clapton, Pete Townshend, Ronnie Lane, Ronnie Wood, Joan Armatrading, Ralph McTell, Sandy Denny, Fairport Convention, and Jim Diamond.
