Ultimajock said:on that extended clip on YouTube, you can hear the Glenn Miller record "In The Mood" faintly underneath the very first WBAP Radio bulletin; the post-War Glenn Miller Orchestra was scheduled to perform in the DFW Metroplex that night, and WBAP was helping to promote that concert. I think on either the WBAP or WFAA aircheck, or both, it's later announced (prior to the official word that JFK had died) that the Miller Orchestra concert had been cancelled for that night...
I believe the Glenn Miller Orchestra reunited in 1956. I think there is a version contiguous to 1956 out there on the road today. I doubt if there are any original members playing (could be I suppose) but I think they still use the same music charts and bandstand stuff from the pre-1944 years.
