Perhaps the official start of the Rock 'n' Roll era should be moved back from 1954's release of Bill Haley's "Rock Around the Clock" to 1946 to this Tex Beneke (formerly with the Glenn Miller Band) song, HEY-BA-BA-RE-BOP. Call me crazy but this sure sounds like Rock 'n' Roll except it was a full 8 years before what is generally acknowledged as the beginning of the Rock era. HEY-BA-BA-RE-BOP
