According to Dennis, when they did the CMN show, Tommy and JY had already hired Lawrence for the upcoming tour (and Dennis was technically out of the band) which only brings even more meaning to what he says during the interview segment.
Reflections on Styx/Dennis in 1999 and the 20 years since? I know we've hashed out plenty and picked sides etc.. so let's not dig TOO deep

I've been lucky enough to see them 11 times, Dennis twice, Gowan twice. They're all great musicians and they all do music I enjoy. Would have been great to see Styx with Dennis at least once though.
