Taylor Swift performed 'Ours,' which appeared on the deluxe version of 'Speak Now,' for the first time last night, and Swift fans in Denver were the lucky ones who got to enjoy the song's live debut. Seated on an old-fashioned leather couch and strumming her acoustic guitar while wearing a peach dress with a full skirt, Swift looked like the belle of the ball -- and she did not disappoint when pulling out the contemplative, emotional song to her adoring fanbase.

Swift acknowledged the fan reaction to the song, posting a tweet after the show. She wrote: "Wow. Denver was LOUD. Amazing crowd. I shall never forget playing 'Ours' live for the first time here tonight. Off to T-party!"

She also performed the 2007 smash hit 'How to Save a Life' by pop-rock band the Fray, who are based in Denver, of course. You know the drill by now. Swift always performs a cover of a song by a local artist when she's cruises into town. She was loyal to the heartfelt original, lacing it with the Swift touch. The mile-high locals sang along in unison, often louder than Swift.
