I too have interesting memories of the "All Christmas" format. Building the Selector Database, for an INSTANT switchover, in case a competitor wished to get there first. Something that was slated to happen on WMC in 2006, until Entercom bought them up. That would have been interesting...
I remember when it was just at night on the station, when I first started. There was also a long standing policy at the time that banned the playing of "Grandma got run over by a reindeer". That policy got vanquished by 2002, by the ridiculous listener demand for it.
I remember the first year it went all Christmas, there were emails posted on the studio door praising the move, and a couple of "Scrooges" letters were posted too...
Anybody remember the "Christmas in Memphis" track recorded for the station in 1998, with Jim Brickman, Clay Cross, Ann Cochran, etc.? I think I still have a copy of that one somewhere, from the burned CD copies that were released, when burned CD's were a new thing... 12 years ago, REALLY?!!
Pam Yates would always decorate the studio with the most Christmas cheer allowed by law, every year!
Good Times, with a repetitive soundtrack...
