Don and Juan were an R&B vocal duo from Brooklyn, NY, consisting of Roland "Don" Trone and Claude "Juan" Johnson. Johnson had previously sung with a doo-wop group called the Genies, who reached #71 on the Billboard pop charts in 1959 with "Who's That Knockin'" on the Shad label. (Contrary to doo-wop lore, Trone was never with the Genies.)
These are photos from concerts where Don & Juan played, so they may be of other bands that played the concert as well.
