Yes, I can wholeheartedly vouch for all that has been said so far. The only time I get the audience quiet is when I sing acapella. Seems like not many people do it in America, in Scotland we did it all the time 'cos we couldn't afford guitars .............Alex, you amaze me, I didn't think anybody outside of Scotland would have heard of that song, let alone sung it unaccompanied to an American audience. There is a hilarious parody of "Up the Noran Water" which I posted as a "Lyr.Add" some months ago. I guess it is only funny if you know the original.
