I was actually giving my response to the leveller's comment in the post immediately before mine which was referring to your post, Joe. It gets tangled up in here at times. I generally try identify who I'm talking about, I missed doing so this time.

I hate the whole idea that particular songs should be shut up in special separated off ghettoes. I am happy that these days the Catholic church has got away from the idea that hymns from other traditions should not be welcomed - though I regret that in the process a lot of hymns that deserve to be sung have been dropped out of use.

Of course it's the case that many songs which have no direct religious reference are only too appropriate to be used in a religious setting, just as it's true the other way round.
