I've had his tape "Single Takes" since, what was it, 2000 or 2001. He sounds VERY much like his father, on tape as well as in person. But definitely more of a contemporary style in the stuff he writes.
Haven't heard hide nor hair of him since, though he kept in touch with a friend for awhile. He lost touch with her, too (or she with him -- he's slippery).
Heard rumors that he's been performing around Canada, though, since I last saw him.
