One of Billy Joel's roadies says a Philadelphia concert was unforgettable -- not for "Piano Man" or "My Life" -- but because a part of the stage allegedly came crashing down on him.
Carl Anderson is suing Billy, claiming the singer is responsible for injuries he suffered back in September 2017 while working as a stage handler. According to the suit, he helped set up for Billy's gig at Citizens Bank Park, home of the Philadelphia Phillies ... who are also getting sued.
In docs, obtained by TMZ, Anderson says he was in the stage area when, out of nowhere, a scaffolding pipe fell and struck him .
