Now I seem to have this memory that I at some point saw a picture with him wearing a red or at least a jacket with a darker color than white or yellow.
Well I guess I got my question answered then, thanks all.
I had browsed through every concert with a photo on Queenlive.ca and I checked about 60 pages of FM pictures here on QZ in order do find an answer. My guess is that it was a B&W photo with a much darker looking yellow jacket that I had seen all those years ago.
