Bon Jovi will now play a double-header in St. Paul, while Slayer and Megadeth have set a makeup date for this week's postponed concert.

The "Livin' on a Prayer" hitmakers are still living it up as one of the concert industry's top draws and were able to add a second night at Xcel Energy Center, April 8, to go along with its nearly sold-out April 7 show. Tickets ($29.50-$131.50) go on sale Saturday at 10 a.m.

Slayer's vocalist/bassist Tom Araya should have plenty of time to recover from his tour-postponing back surgery before the Roy Wilkins Auditorium gig with fellow thrash-metal vets Megadeth and Testament, now set for Aug. 21. Tickets to the original concert will be honored, and more are now on sale ($10-$59).
