The four hour music marathon started with Buchanan and then ramped it up with the superbly talented American Carrie Underwood belting out some of her biggest hits.
Underwood was accompanied by no less than five guitarists, and electric light show behind her on the giant screens.
Her vocal range was exceptional though a little drowned out by the sheer volume and thumping bass of the music.
Her rendition of Dirty Laundy, a good old country song about cheating, got fans fired up, while her acoustic tribute to Dolly Parton through I Will Always Love You was a nice touch.
