Sabby Lewis has become a legendary jazz pianist and band leader in Boston. He organized his first band in Boston in 1936. In 1942 his musical talent was recognized when he was chosen to perform a Sunday-night NBC radio broadcast. In the 1950s and 1960s he played on Broadway in New York City and at leading clubs in New York and Boston - in Boston at the Savoy (where he first introduced jazz for listening in 1940), the Hi-Hat, and at Wally's Paradise. For decades Sabby Lewis's bands played for ballroom dances all over New England. At age 75 Mr. Lewis is still at the piano - more recently at the Westin Hotel and in The Lounge at the Ritz-Carlton Hotel in Boston.
