It is very true! From akronlife.com:
[Luigi’s Restaurant owner Tony Ciriello] was just a kid in the ‘70s when his uncle Mickey Ciriello rescued the broken-down band from storage…The restaurant’s electrician, Butch Pastik, did the rewiring and a repairman at an old jukebox warehouse in Cleveland got the mechanical parts working again. Then Mickey and some friends began looking for characters to replace the old foam band members – brittle and crumbling from dry rot.
After discovering that Ken dolls and GI Joes didn’t work in the bandbox, Mickey settled on some 8-inch action figure Superman dolls. They were just the right size, and their arms were flexible enough to be posed with the musical instruments. Then he decided to swap out the male lead singer for a more glamorous blond Barbie…Mickey hired a local seamstress to create tuxedos for the band and created mop-top wigs for their heads…
For now, a new Barbie doll has replaced the ‘70s lead singer, but the male band members from the first restoration live on. One has been wearing a Superman suit under his tuxedo for all these years. In the tradition of protecting Clark Kent’s real identity, Tony won’t say which one is the true Man of Steel.
