My friend Peter Millhouse was an RAF fighter pilot. In the mid-Sixties he left the service to work in film and TV in Swinging London, as it was only half-jokingly called, cutting a dashing figure around the King’s Road. In early 1969 he was working for Michael Lindsay-Hogg, the director of Let It Be, and claims to have been on the Apple rooftop for the Beatles’ famous, impromptu final concert.
