Duffy - Mercy (Live On Later With Jools Holland)

There isn't any other new up-and-coming artist that has had as much exposure as Welsh singer Duffy has received in the last month. She's about to release new single Rockferry on Monday (video link and review link) and she's also in the studio with Bernard Butler finshing up her first album (watch the pair in action here).

Now Duffy has just appeared on Later with Jools Holland where she performed the currently unreleased Mercy and the video can be watched below. We also just found that Mercy will be her next single too, which I imagine will surface in late Jan / early Feb.
