And, just to put any doubt aside, I can confirm that the singles from JWU are all identical to the album tracks, with not a jot of difference.
Reasonably simple to prove... Import both single and album track into an audo editor (Audacity will do if you want one for free). Line one up against the other (zoom in lots, and pick a part of the waveform that's distinctive, so easy to line up. Invert one of the tracks, and then play both. In theory, if you've lined them up perfectly, you'll hear nothing, but in practise, you'll hear a tinny rendition of the song which is caused by the mirror images cancelling each other out. And material differences between the two tracks, a slight remix, say, will stand out like a sore thumb.
The lengths I go to to prove a point...
