Ok - I was the guest at 11.16 on 2nd June.

I think the chorus went....

If we drink we shall die, if we don't drink we shall die
So we might as well say what the hell and raise our glasses high
Whatever your name you'll be dying just the same
So you might as well say what the hell and join us in a drink - hey!

as for the verses...

Some men are lovers, they work under covers
As from ladies bed to ladies bed they leap
But the man I'll drink to, the man nobody drinks to
Is the man who only goes to bed to go to sleep...

...is all i can remember I'm afraid
