One Trick Pony (1980)

If Paul Simon had never managed a hit after “The Sounds of Silence,” he might have ended up like the lead character in One Trick Pony (1980). Instead, Simon is only fantasizing as he stars in his own script about a one-hit-wonder folkie with a bad marriage and a dying career. Fortunately, even a has-been rock star gets to still-be with plenty of gorgeous naked groupies--including hot older babe Joan Hackett and sweet young thing Mare Winningham.
