Fred with Trooper Pal Peter Hadley And three unknown civilians

Having done extensive research, just from the photograph and knowing that my Grandad was in 'The Recce Rascals Concert Party', the family were delighted when I was able to name my Grandads Trooper Pal, as Peter Hadley. I managed this with trial and error via the Ancestry site, having made the assumption that his age was that of around my Grandads, and by contacting several families who had trees with a male of that name around that age. My Grandad was killed in action and that is why we had no idea who was in the photographs or any ideas of what he got up too. I must also add that not only was it extremely rewarding to learn that Peter Hadley was not only a Trooper Pal of my Grandads, but that they actually performed together in the Concert Party too! Sadly, Peter died a few years ago, but the Grandaughter I am in contact with has shared several stories about their times together as they remember him speaking about 'Freddy' Amazing! Also - The family have NO photographs of Peter in Uniform......they have now!! I am still trying to discover who the three civilians are in this photograph, and indeed where it was taken. Any suggestions would be most welcomed. Thank you for looking.
