Xterminator's right, Scott was in a car accident last spring and hurt his back and has had to medicine because of it. I've hurt my back a few times and it's very painful. I give him a lot of credit for touring like he did with the pain, it must not have been easy.
Scott is no longer married and I think he and Hillaree (his ex-wife) were married in January 1998 and got divorced sometime in 1999. I believe that's remember from the Behind the Music special on VH1 and articles that I've read.
Hope this info helps and welcome to the board.
