By January 1967, Epstein was under pressure from the Beatles' record company to release a new single by the group. Martin told him that they had recorded "Strawberry Fields Forever" and "Penny Lane", which, in his opinion, were "two all-time great songs". The decision was made to issue them as a double A-side single, a format the Beatles had used for their previous single, "Eleanor Rigby" / "Yellow Submarine", in August 1966. The Beatles produced a film clip for "Strawberry Fields Forever", in a continuation of their policy since 1965 of avoiding the need to promote a single with numerous personal appearances on television. It was filmed on 30 and 31 January 1967 at Knole Park in Sevenoaks, Kent. The following week, the band shot part of the promotional film for "Penny Lane" at the same location.
