Brandy Sour Recipe
I once bought the exact products that were used from the bar at Akrotiri. The result was close and I think the difference was the ice and the plastic jugs.
It was:
Anglais Brandy
The NAAFI version of Angasturo Bitters
Kean Lemon Squash
Schweppes Soda Water
Crushed Ice
Can't remember the mix.
