Maxwell Street on Sundays drew thousands of shoppers, merchants, and tourists, and scores of blues performers, folk singers, and gospel singers, including some of the most famous names in the blues.
All of the recordings were edited for use in the film. There is not a single uninterrupted performance in the film. Miraculously, all of the original Nagra sound recordings exist in their unedited form, although the video portions of the musical outtakes from the film are presumed lost. An unauthorised version of a portion of the music from copies of the original tapes was released in 1980 (Robert Nighthawk: Live on Maxwell Street--1964, Rounder 2022).
Many unrealeased performances and the superior sound of the original tapes are available again for the first time since 1964.
