The Rainbow Bar and Grill was founded in early 1972 and at the time, the word "rainbow" signified peace and freedom. The Rainbow became known as a hangout for rock musicians and their groupies. Notable regulars at the Rainbow in this period include Keith Moon, Alice Cooper, Micky Dolenz, Harry Nilsson, John Lennon, Ringo Starr, and Neil Diamond. As musical trends on the Strip changed towards heavy metal in the 1980s, the Rainbow followed suit. Members of Motley Crue, Poison, and Guns N' Roses frequented the bar.
