I came up with a quick list of all of the bands I could remember meeting...if I only met one or two members, I listed them i parentheses. Otherwise, I met the whole band. There's some good ones in here (Winger for example). I have been going to shows for close to 20 years and have worked in all kinds of areas in the biz, so I have met a lot of bands. Most I have gotten autographs or pictures with just for the memories.
