Robert Graves mentions Cosher Bailey being sung by his fellow troops in WW1 in his biog Goodbye to All That.

Guys who were going off to face death and were probably pretty frightened. And presumably we're talking about Welsh guys who were from the chapel infested valleys where enlightened sexual attitudes were something of the future.

The thing is we have so many tabus about sexuality- it's no wonder we get it wrong and sometimes we appear base and don't always behave and express ourselves as well as we might.

I think what I'm trying to say is that the urge to sing dirty songs is probably how some of us need to approach the dirty subject. It's the life force, that gets most of us born.....a bit of respect please.
