Technically, there's 4 versions of this song. The original, the radio mix, the instrumental and the box set version. The original and the radio mix are pretty close to each other, I only hear a bit of a warmer mix in the radio version and the addition of some piano, not by Dave obviously.

As to the box set version, I will never understand it. They use a different vocal take completely, take out some backing vocals, add a guitar and either drop it half a key or raise it, I can't remember. Personally, I think the box set remix ruined the song but meh. I did like how they incorperated the string outro that was in the instrumental version though.
