Lay Your Hands On Me definately the best one - real rocking.

Twist And Shout the worst - as played in Giants Stadium on Bounce tour (Aug 8 2003)

Livin' On A Prayer is also great as a opener - good idea to start the show with megahit but I think it works better as a closing song for the main set. In my opinion the worst usage of the song was on the Bounce tour (and on some concerts on OWN tour) - as a third or fourt song.

Next goo is One Wild Night - maybe because of the title.
