Hmmm, Ralph McTell...sure I've either heard some his, or more likely someone doing covers of his stuff. Quite possibly the aforementioned Mr. Gallagher. Name a couple of tunes?
Jam sessions here are unfortunately unlikely, but when I'm finally relocated, you'd be welcome to visit up north. My playing is no longer rusty - bloody well shouldn't be, the amount of time I've been putting into it!
