I've never had any luck finding anything on him post CO. I guess he's rattling around somewhere doing something.
I wonder if there's any regrets on his part? I guess sure, there hasn't been any big money, but there's been some beautiful albums.
It's a subjective thing ofcourse but me personally, I far prefer their output post Henderson, Campbell's songwriting really seems to have come into it's own on the subsequent albums. Whether this would've happened if he was still there or not, who knows, I'd like to think so. BUt perhaps there wouldn't have been as much room for it to happen, maybe not as much impetus for it to happen?
This is all pure speculation though.
I wonder if there's any bad blood? I got the impression the split wasn't pretty or amicable?
