The latest version of BBC Radio's Soul Music (may its tribe increase!) is about Gloria Gaynor's "I will survive."
We learn that in 1978, when she recorded the song, Gaynor was, in fact, wearing a medical brace following emergency surgery on her back after an accident that could have left her paralysed for life. “I’d been on stage and fallen backwards over a monitor and ended up in hospital."
This is totally amazing to me. Phil played bass on a tour with her in the 80s. As a rule he stands to the left of the drummer so he can lock in to the tempo from the high hat, On this occasion though he gradually found himself (and not in a weird way) drifting away from his station and taking the time from her shaking her booty.
This was after 1978 surgery to remove a ruptured disc and fuse two of the vertebrae in her lower spine, but before she went under the knife again in 1997 to correct the spinal stenosis caused by the initial operation. Two more procedures followed in 2018.
What a woman.
