* Not likely, but I think it's a great opener. I almost dropped it, put limelight as the opener, and popped Losing It in the middle somewhere, but I don't think they'll play Losing It even with the strings... An electric violin solo is a different thing from a string section. In all reality The Necromancer is probably about as likely as BD. I think Limbo as the drum solo intro makes sense, and there will be some sort of video or something dedicating it to Freddie.
The last 3 songs out were Freeze as part of the Fear Trilogy, Afterimage, and Xanadu. I think Xanadu is likely, and probably a couple songs of CA will get dropped instead, but I really want the whole thing as a piece on this tour. I couldn't figure out where to put Afterimage.
