I've just heard the full version of the song. It's quite good, running about four minutes, it'll probably be edited a bit to fit the titles. Which are normally about 3 minutes long.
Song found here.
Not sure how long that link will stay active, but since the song's premiering in a few hours anyways, if you miss it there, you'll be able to hear it anyways.
Thanks Aldo. I'm loving this song. It's like 3 for the price of one. Adele is releasing something new, it's the new Bond theme, and it's going back to the classics, with the Bond theme intermixed in there.
