She will appear on a TV show before heading to Cologne on Saturday (25Jun11) to sing the song for boxing fans ahead of the world middleweight championship bout between title-holder Felix Sturm and challenger Matthew Macklin - and she plans to psyche herself up by watching fight movie Rocky before the gig.

In a post on her official blog, Chisholm writes, "My first performances of the track will be at the end of this week. I'm doing the track acoustically on Friday on German TV and on Saturday at the Felix Sturm v Matthew Macklin boxing match in Cologne, it'll certainly be the first time I sing in a boxing ring, so maybe I'll watch Rocky before I head out there for a bit of inspiration!"
