The music video for "Free as a Bird" was produced by Vincent Joliet and directed by Joe Pytka and depicts, from the point of view of a bird in flight, many references to Beatles songs, such as "Penny Lane", "Paperback Writer", "A Day in the Life", "Eleanor Rigby", "Helter Skelter", "Piggies", "The Continuing Story of Bungalow Bill", "Strawberry Fields Forever", "Doctor Robert", and "The Fool on the Hill". Between 80 and 100 allusions to the Beatles' story, music and lyrics in the video have been estimated. Although the bird can be heard at the beginning of the video, it is never seen. Neil Aspinall (Apple Records executive at the time) said that this was because no-one could agree on what kind of bird it should be. Pytka had to send his ideas to McCartney, Harrison and Starr, as well as Ono, to make sure they all agreed before he could proceed with the filming of the video. Derek Taylor (ex-Apple Records executive) sent a two-page letter to Pytka confirming that he could proceed, and personally encouraged and supported Pytka's ideas. The video was filmed in as many authentic locations as possible: Penny Lane was made by Pytka's art department to look as it was in the 1950s, and other locations filmed were The Liver Building, and Liverpool Docks (as a reference to Lennon's father Alfred Lennon).
