Mary Ouellette of Loudwire has interviewed Mötley Crüe drummer Tommy Lee about his band's upcoming 12 show residency in Las Vegas at The Joint inside The Hard Rock Casino in February 2012. An excerpt follows:

When some people think Vegas, Cher and Celine Dion come to mind. How are you planning to change that mindset with this groundbreaking run?

"I guess people should probably lose all preconceptions, because we have set up to make it something that nobody’s ever seen or participated in before. It’s going to be something that’s very interactive; by the time we’re done with this, you’re going to see the show, wear the show, drink the show.

It will definitely be an experience, we’re taking over the entire Hard Rock, and the show won’t only be inside The Joint, if you know what I’m saying. That’s our mission here, to do something really different, that no one else has ever done. So don’t even think about those other things; those are terrible! It won’t be anything like that, I guarantee you!"

You’re asking fans for feedback on your website; any chance the band would open up the set list to fan participation to mix it up a bit?

"We’ll have to switch up the set a lot since we’ll be doing several shows in a row, we’ll have have to change things up because on the weekend people might come see us a few times. Some maniacs that I know will probably come every night, so we’ve already talked about making some different portions of the show that will require a lot of change; that’s probably going to happen, I’d imagine."
