I had a video cassette of a Grady Mathews 1 pocket instructional tape that I think might have been one of his first ones on 1 pocket, and I gave it to a guy at the pool room I used to play in a long time ago. Looking back I realize it was very good and would like to get another copy of it in DVD. I could start an internet search but thought if I asked you all that it might be faster. Anyone know a good place to start looking? Would really appreciate any help. Thanks in advance.
