As you will hear, I was looking at one of the amazing photos in the Barry Plummer Calendar (available now from YesMusicBooks.com) recently, when I noticed something peculiar about Chris Squire. I think what Barry has captured is a unique moment in Yes concert history. I don't think Chris ever did this in any other situation than the shows on the 1975 Relayer tour - and maybe not all of those performances. I have watched the QPR video many times but I hadn't realised exactly what was going on until I saw this photo and then re-watched the QPR performance.

After watching that QPR version, Mark and I also took a careful look at a much later version, from the Yes Acoustic video. It's very different.

I've included a heavily watermarked version of the Squire photo in the show notes for this episode but if you want to enjoy the full-quality version, you know what to do. Order the calendar now while there's still time to receive it before the New Year.

So, what do you think I'm on about? Stay tuned for the full rabbit hole exploration with Mark.
