Emily Linge covering of one of the finest songs to emerge from the 1960s - Procol Harem's Whiter Shade of Pale.
I remember the song well. I hadn't given it a listen in some time, so dipped into my music collection and discovered, with a shock, that the versions I have are in magnificent mono. As far as I can tell, it wasn't until the release of a fiftieth anniversary album that a re-mixed stereo version first appeared. So, so weird hearing the drums, bass, and organ separately. It'll take some getting used to.
I went over to Wikipedia for details of the recording and noted that some contributor has identified the organ intro as based on a Bach's Orchestral Suite No. 3 in D Major. The same article quotes Gary Brooker as saying "If you trace the chordal element, it does a bar or two of Bach's 'Air on a G String' before it veers off. That spark was all it took. I wasn't consciously combining rock with classical, it's just that Bach's music was in me."
A likely story. The article does record, accurately. the copyright dispute over the organ part. Not by Brooker at all, but by Matthew Fisher, so who was Brooker kidding?
I got to see Procol just once, on a double bill with Deep Purple. Great concert!
