Factual error: When we see Elton John's father Stanley in RAF uniform at the beginning of the film he is wearing other ranks' uniform. Stanley was commissioned in 1944, three years before Elton was born, and served as a commissioned officer until his retirement as a squadron leader in 1963. He should be wearing officer's uniform.
Factual error: A 1976 Chevy Blazer is seen as the duo first enter the Troubadour in 1970.
Factual error: Elton's family home in Pinner is fitted with double glazing which is visible in the scenes when the cast are dancing outside in the street. Double glazing did not exist in 1950s England.
