Sunday night's Academy of Country Music Awards featured duets, impromptu songs, sexy numbers and even a live wedding.

Carrie Underwood got the night started with a performance of her song "Good Girl." Song of the year winners Eli Young Band had an early performance slot.

The party truly came when Toby Keith walked through the crowd singing his surprise hit, "Red Solo Cup" with the help of Carrot Top.

Actor-comedian-banjo player Steve Martin paid tribute to the late banjo pioneer Earl Scruggs, and country met R&B-pop when ACM co-host Blake Shelton performed with Lionel Richie as the show's closer.
