The CMT Awards were filled with surprises beyond the upset wins tonight. Some of the performances featured musical cameos we weren't expecting, and some of the presenters weren't exactly Nashville regulars.

Keith Urban kicked off the show with his raucous 'Raise the Barn' duet with Brooks & Dunn. Hank Williams, Jr. made a surprise appearance with Brad Paisley on the fitting song for both, 'I'm Still A Guy.' And Sugarland invited tourmates Little Big Town and Jake Owen on stage with them for a cover of the 1986 Dream Academy song, 'Life in a Northern Town.'

Presenters at the awards included several non-country music celebrities, such as Paula Abdul, Snoop Dogg, Sisqo and actor Tim Daly. But perhaps the most shocking appearances were by the three top Presidential candidates: Barack Obama, John McCain and Hillary Clinton. The politicians appeared via video in a hilarious skit that featured them all calling Miley Cyrus for tickets to the CMT Awards. The clip also featured Trace Adkins trying to get his kids into the show to see Miley. Not even Donald Trump, in another surprise cameo, could help him out. But at the end of the video, Adkins scores tickets from a scalper, who just happened to be Miley's dad, Billy Ray Cyrus.
