Bob Dylan and the Band caught on b&w half-inch open reel videotape at the Isle of Wight Festival on August 31, 1969. Dylan had rejected an offer to play at Woodstock to headline the festival.
Allegedly this was shot by a friend of John Lennon and Ringo Starr (who can be seen in the audience here). This makes sense because a) only someone relatively wealthy would have had access to a half-inch open reel video-recorder at the time and b) whoever shot this was right up front.
