My better half is a big fan of Bach. He is from that period.
I imagine Bach was played at Christmas time too.
My high school choir sang a lot of Bach. Not any more. Too religious. Times have changed!
The funny thing is that Telemann was much more popular in Bach's lifetime. He was a fairly obscure music director (although his post in Leipzig was a prestigious one) while Telemann was an international sensation.
You just can never tell what the verdict of history is going to be . ..
