Interesting to find out where this photo was taken. I am pretty sure it was in the beginning of the US tour although I could be wrong. I say so because of what Paul is wearing. I have not all Euro dates covered but to my knowlegde Paul only starting wearing the red top during the USA tour. The bands stage clothes started to change during the US tour. Looking at Gene, he's still wearing his typical Euro outfit. He kept wearing this till January orso before switsing to a black or pink silk shirt.
Based on this my best guess is this photo was taken in December 83 / Early 84 in the US. But where ..... ?
