New Year's Eve revelers at the Mala Wailea in Hawaii were treated to something special to kick off their 2012 -- well, besides being in Hawaii.

The Wailea Beach Marriott Resort & Spa hosted a charity gig this past Saturday night that saw comedian Tom Arnold emceeing a concert featuring Alice Cooper and guests such as Weird Al Yankovic and Michael McDonald.

Among the unannounced special guests was Aerosmith frontman Steven Tyler, who performed a cover of the Beatles' "Come Together" with Cooper. You can check out video of the performance below.

Tyler also reportedly performed "Sweet Emotion" and "Walk This Way."
