When I was in the local post-surgery ward just before Christmas, a trio of schoolgirl violinists came in, set up their music stands and played some nice tunes. They told me the only one I didn't recognise was French, but all were Christmas carols; sans words and dancing, but carols all the same. They apparently had the approval of the authorities but were not supervised directly and I know for certain their audience contained some atheists.

Perhaps it's just as well they were celebrating rather than engaging in any other type of activity. BTW, they were very well received by all and sundry.

Cheers, Rowan
