Has 100 FM The Pike ever played any Christmas songs on the actual day, December 25th?
I live in Worcester County and listen to The Pike. If I recall correctly (which I probably don't), they may go all Christmas-ish from roughly 6pm Christmas Eve through Christmas night. Sister station WORC-FM, in their previous incarnation as Oldies 98-9, usually flipped to all Christmas at least a couple of weeks before. They flipped to a country format a few years ago (Nash Icon 98-9). Not really sure what they do now. Other sister station, 104-5 WXLO-FM, usually starts mixing in Christmas music a few weeks before. Pretty sure they go all-Christmas a week or two before as well.
I checked a thread here on this board from a year ago. Worcester's WSRS (not the same company as the other three) flipped to Christmas on November 15th.
