Ken Kessler from the Sounds of Christmas talks about "Jingle Bell Rock" and how different artists release Christmas music. He also talks to singer/songwriter/consultant/blogger John O'Leary about some of the lesser known things about the writing of "Jingle Bell Rock", including the conspiracy theories about what might have happened (which probably did happen) in which careers were ended and lives were threatened. They also talked about the songwriting story behind "Have Yourself A Merry Little Christmas", and how that song evolved thanks to Judy Garland, and then, several years later, thanks to Frank Sinatra.
