Sound guy?

Walking to the bank this afternoon and on the corner of Hanover and Thistle I again ran into the filming of 'Sunshine on Leith' a musical about the Proclaimers. This time I actually managed to see some action rather then lights, camera, and no action. I was too polite to snap a picture of the actual action but did shoot what I think is a cold looking sound guy.
For the curious the labels on the sound inputs are:Rab, Harry, Eildh, Liz, Ronnie, Music, Jean, Yvonne
