I came across this clip that I had never seen before of a quasi-live performance of the Beatles singing Hey Jude in 1968 as part of a video promotion for the song. The clip first aired on a show hosted by David Frost that begins with them goofing around and ends with the studio audience of 300 people crowding around the group to join in the famous ending. According the person who uploaded the clip, the performance was a mixture of live and lip-synching.
To help with the filming an audience of around 300 local people, as well as some of the fans that gathered regularly outside Abbey Road Studios were brought in for the song’s finale. Their presence had an unlikely upside for The Beatles in their long-running saga with the Musicians’ Union in that the MU were fooled into believing the band were playing live, when in fact they were miming for the vast majority of the song. Paul, however, sang live throughout the song.
The video was first broadcast on David Frost’s Frost On Sunday show, four days after it was filmed. At that point transmission was in black and white although the promo was originally shot in colour. It was first aired in America a month later on 6 October 1968, on The Smotheres Brothers Comedy Hour.
