On what I think will be the enduring strength of songs like "Summer Of My Dreams" and the "Garden Song" I think Dave Mallett rates a mention. Maybe he doesn't spring to mind here 'cause his renown is from others doing his songs.

Murray,
I too love Jack Williams. I'm a latecomer to this amazing musician -- only found out about him a few years ago because he shares a label with Small Potatos.

I can't think of a man whose music moves me any more than Chris Smither -- the multiple mention here is well deserved.
