Forever Plaid is a musical comedy written by Stuart Ross in 1990. The critically acclaimed show is an affectionate revue of the close-harmony "guy groups" (e.g. The Four Aces, The Four Freshmen) that reached the height of their popularity during the 1950s. Personifying the clean-cut genre are the Plaids. This quartet of high-school chums' earnest dreams of recording an album ended in death (literally and indeed, symbolically) in a collision with a bus filled with Catholic schoolgirls on their way to see the Beatles' American debut on The Ed Sullivan Show. The play begins with the Plaids returning from the afterlife for one final chance at musical glory.
