Carrie Underwood and Steven Tyler Rock the ACM Awards

It was another big night for the stars of country music at the 2011 Academy of Country Music awards.  But, for me, a rock-and-roll guy stole the show.  Steven Tyler from Aerosmith (and American Idol) joined Carrie Underwood on stage as she sang her song "Undo It."  Then things ratcheted up a notch as the duo kicked into to a frolicking, flirty version of Aerosmith's "Walk This Way."  Good stuff!
