Watch/hear Keira Knightley sing

Keira Knightley's latest period piece, "The Edge of Love," has an U.K. release date of June 27, and while an U.S. date doesn't appear to have been set, you can bide your time with this clip of Knightley singing in the film.

"The Edge of Love," which also stars Cillian Murphy, Sienna Miller and Matthew Rhys, is a romantic drama inspired by the life of Welsh poet Dylan Thomas (played by Rhys). A while back, the Daily Mail had a bit more info on the music in the film, reporting that Knightley sings such songs as Irving Berlin's "Maybe It's Because I Love You Too Much" and "Drifting and Dreaming."

The paper also reported that the film opens with Knightley singing "Blue Tahitian Moon." That appears to be the clip that hit the Internet, courtesy of the U.K.'s "We Are Orange," and then was re-clipped by a Knightley fan site.

And finally, also according to the Daily Mail, the film will additionally feature vocals from Madness singer Suggs, Siouxsie Sioux, Beth Rowley and Patrick Wolf.

For those overseas -- and those willing to pay import prices -- the soundtrack will be released June 16. (Or June 24, depending on which Amazon territorial site you believe.)
