Whiter shade of Pale: Johnny Winter, or some blokes pasty white arse?
...Oh! The song!...I see
U must mean the Procol Harem original one seeing how everybody and their mama covered it
Anyways, although I'm only listening to it on a small mobile device, I believe I hear very simple piano backing every count
I.E. If you counted rhythmically 1 and 2 and 3 and 4 and...1 and 2 and 3...etc..
On every count there is a piano which sounds like it has some heavy sustain backing up the foundation of the rhythm
While the organ does all the flourishing
At 1:40 ish I thought I heard the first entrance of the guitar.
After the 2 min mark, the piano shifts from the simple droning to adding "color"
Along the same lines as before, only in a higher register with a little more chording.
After the 3 minute mark I can distinctly hear some guitar phrasing.
Seeing how its such a popular song you might do well to look up a "tutorial" online about it.
The guitar sounded mainly like chords. But from the version I heard...its all there, just the entrancement (I think I just made up that word) might lead an untrained ear to imagine that its not there.
Either that or you and I are listening to an entirely different version
I hope someone with more conservatory knowledge (I'm self taught, really a novice with music theory) will support this forum post and explain things more clearly
