Carrie Underwood was first, Blake Shelton and Lionel Richie were last and very few dips were found in between. It was three straight hours of back-to-back performances that barely left time for a bathroom break on Sunday night. The 2012 ACM Awards felt more like an all-star jam than an awards ceremony, not that anyone is complaining.

Kenny Chesney and Tim McGraw might have been the highest profile pairing of the night, singing Chesney's next single 'Feel Like a Rock Star.' However, Richie and Shelton and Brad Paisley with the Zac Brown Band were two other collaborations that fans will be tingling from on Monday morning.
