Ashley is known as the Guvnor and so he should be. The wikipedia entry on him is fairly comprehensive.

I have had him on my radio show and met him twice recently and he has been charming, thoughtful and very erudite.

You might care to watch out for his son Blair Dunlop - who is an amazing guitar player and excellent singer. I suppose it is in the genes! (Blair played Young Willie Wonka in the 2005 version of Charlie And the Chocolate Factory)
