I saw the new James Bond movie yesterday and they showed a new promo for Lost featuring this same song so I'm guessing it's the same one.
Most of the footage is the same as the first season 5 promo but there are at least three new clips.
Desmond and Penny, with Desmond getting out of bed and Penny saying "Where are you going?"
Jack in a tuxedo talking to Ben and saying "Okay let's get them back".
And one of John Locke falling from something.
