The night was full of colorful performances, but the anticipation of Garth Brooks and George Strait performing together overshadowed almost everything else.
The three-hour televised show also included performances from American Idol winners Carrie Underwood and Kelly Clarkson, Garth Brooks and George Strait, and Brad Paisley and John Mayer.
