From their web page, News/Reviews section:

"After 15 years without a break, Denny has finally decided that he cannot bear to sit next to Chris any longer and is going to take some time off from the band (well, he told us it was to spend time more time with his babies whilst they were little, but we think anyone deserves a break after all that time!)"

They were over here once, and I really enjoyed their music, not to mention their inspirational insanity.
