What's the name of that really pretty song who's music plays softly in ads for The Life of Mammals? I can't help but recall the words 'silent sigh' in the words, but am not sure. Please help!

Haven't seen the ad myself, but with those words it must be 'Silent Sigh' by Badly Drawn Boy, from the 'About A Boy' soundtrack. Click on http://www.badlydrawnboy.com and got to the Audio/Visual section, where you'll be able to hear a clip.
