Ken Regan (June 15, c. 1940s – November 25, 2012) was an American photojournalist from the Bronx, New York City whose reputation for discretion allowed him close connections with subjects including many musicians, politicians and celebrities. He was the official photographer for the Rolling Stones on several tours in the 1970s. He also was the photojournalist on Bob Dylan’s Rolling Thunder Revue tour in 1975 and the Live Aid concert in 1985.^[1][2]
