The Bay City Rollers were a Scottish pop/rock band of the '70s with a strong following among teenage girls. The origins of the group go back to the formation of the duo the Longmuir Brothers in the late '60s, consisting of drummer Derek Longmuir (b. March 19, 1952, Edinburgh, Scotland) and his bass-playing brother Alan (b. June 20, 1953, Edinburgh). They eventually changed their name to Saxon, adding singer Nobby Clarke and John Devine. Then they changed their name again by pointing at random to a spot on a map of the United States: Bay City, MI.
