Taylor Swift gave her fans in Denver, Colo. a big treat on Tuesday. Not only did she cover the Fray's hit 'How to Save a Life,' but she also treated the audience to the first live performance of her 'Speak Now' song 'Ours.'

The 21-year-old star has been dutifully tipping her hat to hometown heroes, covering everyone from Justin Bieber to the All-American Rejects on her North American run. This time, she chose to do a rendition of the title track from the Fray's debut album, a song which stayed on the Billboard Hot 100 for 58 consecutive weeks.

The Denver show was also where Swift chose to sing her song 'Ours' live for the very first time. The tune is included as a bonus track on the deluxe version of her 'Speak Now' album.

"You know how when you fall in love sometimes people try to come between you and kind of whisper in your ear and give you doubt?" she posed to the audience before the performance. "This is a song about that ... This is a song about how you shouldn't listen to that."

Fans who haven't been able to catch Swift's live show will be able to experience it when she releases her ‘Speak Now World Tour Live’ CD/DVD combo on Nov. 21. It will include all 17 songs from the singer’s tour set, as well as bonus footage from her time on the road.
