I was quite disappointed by his work on the starland ballroom show. Not exactly by his playing, but mostly by the sounds he used - they were aweful und sounded misplaced somehow.
I'd rather consider him a friend of Jon than a professional. It's kind of like Bobby replacing Richie in Chile some years ago - just not the same. I'm sorry for those who won't have Dave.

BTW, when did DB forget the lyrics to In these arms?

Bryan's a solid player and singer and never seems to have a bad day. The sounds he uses are very an important part of the anthemic trademark BJ sound.
So I absolutely don't get how him not being there should be a blessing in disguise.
