This photograph hangs on the wall of a significant financier. We can see it’s McCartney and Jagger in a recording studio. Three questions. Who is the guy with the neckerchief biting his nails? Which studio are they in? What year is it?
Over to you…..
Update – Is this the same guy (the one on the right)?
And this guy (on the left)?
and left here….
conclusive proof:
.
The man in the shirt is Glyn Johns.
Is this the studio? From 4.45
Still looking for confirmation of the year and the studio.
Sound Of The Hound 
I had the chance to work with Glyn Johns in 1979. I was working for a remote truck called FEDCO Audio. We traveled to Hamilton and Toronto Canada to record a live album for Joan Armatrading called Steppin Out. Glynn Johns was the producer. He is well known for his 3 mic technique for recordings drums. I have used that mic setup many times. It was a great experience working for him.
