CANADA – MARCH 04: Massey Hall 03/05/1972 — Spoofing the golden years of '50s rock in their glittering suits and greased hair, New York band Sha Na Na had a capacity audience shouting for more in two concerts at Massey Hall Saturday night. They got three encores in the first show and standing ovations as people danced in the aisles. The group was founded as a gimmick by university students until they found their satirizing of rock stars paid well.
