My 80 something barber use to have a shop in Newark,NJ. He use to tell me stories of the mob, Frankie Valli and Joe Pesci. He said before Valli was famous they all use to ask Frankie to sing high and they would all crack up how high an octave he could reach. When I saw the Jersey Boys on Broadway some of my barber's stories he told me before the play was ever conceived was in it.
