Not much is known about the Bob Corwin who played tuba on several Elvis Presley soundtracks in the mid '60s, a distinctive credit in itself even without biographical fodder. It does not seem to be the jazz pianist of the same name, although some brave researchers think it might be his brother, the one mentioned by several biographers as a big-band player but never actually provided with a name. That concept only works if both brothers were named Bob. Even without a solid identity, one thing has changed in the status of this tuba toter. When the soundtracks to films such as Hawaiian Style Elvis were first released, the studio musicians featured were generally not credited. This all changed with a special RCA reissue in the early '90s. ~ Eugene Chadbourne, All Music Guide
