It's been obvious for a long time, if you pay close attention, that Steve had very little interest in the band anymore. He didn't want to make new music, didn't want to do longer sets or more shows, and he was basically just paying the bills. The chances of getting new music from Kansas, and a more varied setlist even, just skyrocketed. I'm not bashing him (he's my favorite singer), but that's just how it is.
