I haven't been on here for a long time, so I don't know if this subject has come up before. It probably has, so forgive me for asking again! I was on barnesandnoble.com searching under Bon Jovi and Mark Bon Jovi popped up. He is a track performer and guitar technician on 2 Enuff Znuff cds. Has anyone heard of this guy? I'm just curious. Once again, sorry if this has been covered before.
