According to an interview on Access Hollywood via
http://www.nickslive.blogspot.com/, Stevie says "Without You" will be released as an FM song. She sings I think part of the second verse! Stevie also goes on to say she wrote it about Lindsey. I didn't know which one wrote it until now. Also, Mick says this is the fastest selling FM tour in 24 years (since Tango in the Night?). Stevie says she knew when they were recording the new songs.... the tour was going to be huge, and says it was like "witchery" that she knew. You can hear the interviewer chuckling, but whatever....that's our Stevie.
