Although this is a beautifully melodic song by David Bowie, who should get credit, people often overlook the piano arrangement, written and played by Rick Wakeman.
i don't get it.. it just sounds like a very well executed straight cover.. love his jazz improv stuff, don't get his pop covers.. horses for courses i guess
I think you need to listen again. It is not a straight cover in any way. I'm new to music theory/harmony but I think the big difference in this one compared to the orignal is called harmonic movement.
