In many cases you may be right, Animaterra.. there may be a heavier programming going on during the Holidays than during the dead months of the winter. My wife and I do a monthly program at a health care center, and there is a real desire to hear live music and share time with people who show that they care about you, whatever the season. If people do feel moved to offer music at a health care center, I wouldn't assume that they have heavy programming in December. Some do, but some don't. Or, it may be a small Christmas party for the residents hosted by the staff, which isn't significantly different than the Birthday parties most places do every month.

One thing you can be pretty sure of. Very few places have too much live music...
