They do a few songs - Tears Are Falling and Lick It Up are the main ones I've seen them do more than once, and they seem to be doing War Machine on their current tour (at least at one gig anyway).
I'd love it if they toured doing their 80s/90s stuff but I doubt it'd happen. They'd probably have to take the make-up off so that the casual fans don't show up expecting the hits.
