The REAL reason Tommy came back to Styx in 1995...

from (http://www.guitarnoise.com/article.php?id=145):
Guitar Noise: What prompted your return with Styx?
Tommy Shaw: Timing is everything. Damn Yankees had taken a break. Actually we had been dropped by the new Warner Brother's brass who decided to get rid of the older acts and sign only new ones. The Goo Goo Dolls were the best of that new regime's signings. So suddenly I was available, not looking at a Damn Yankees recording project OR a tour.
(Monker proven wrong... again.)
