I knew Santana was a resident act, but I wasn't aware the other three were. The approval list shows them each with a single date: The Killers as April 17th, Bon Jovi as April 25th, and Kenny Chesney as April 26th. I was just curious and looking for a little info. I love collecting the HR and don't want to miss them if I can avoid it. Was just wondering if they may be released sometime in the next couple weeks or so when I'm going to be in Vegas
