Let the Good Times Roll is a 1973 rockumentary concert film directed by Robert Abel and Sidney Levin. It features numerous stars from the American pop and rock music scene of the 1950s.
The film ends with a rare, and apparently impromptu, duet between Berry and Diddley, who had recorded together before, but were not often filmed on stage together.The film uses split screen techniques to contrast the performers appearances in the 1950s and in the 1970s as well as utilizing clips from 1950sera films such as I Was a Teenage Werewolf. Vincent Canby, writing for The New York Times, described it as avantgarde. ........
