Like his main rival, Benny Goodman, and other leaders of big bands, Shaw fashioned a smaller "band within the band" in 1940. He named it Artie Shaw and the Gramercy Five after his home telephone exchange. Band pianist Johnny Guarnieri played harpsichord on the quintet recordings, and Al Hendrickson played electric guitar. Trumpeter Roy Eldridge became part of the group, succeeding Billy Butterfield. In 1940, the original Gramercy Five pressed eight records, then Shaw dissolved the band in early 1941. The Gramercy Five's biggest hit was "Summit Ridge Drive", one of Shaw's million-selling singles. His last prewar band, organized in September 1941, included Oran "Hot Lips" Page, Max Kaminsky, Georgie Auld, Dave Tough, Jack Jenney, Ray Conniff and Guarnieri.
