I've been trying desperately to find out the same thing! Must have just been commissioned to do the advert.. It's beautiful though. Would love to find out. Let me know if you do.
Like Gilo, I have also been looking everywhere to find out who sings this song so beautifully, I think you responded to my question about this on Yahoo answers Gilo :) If I find out I will let you know right away.
Hi - it is Dawn Landes singing a Neil Diamond tune.
Her CD's are on CDBABY.com. We may be able to get the song recorded in full later - working on it. Until then you can listen to the 30 sec film on vicks.co.uk
