I remember hearing this as an Air cadet in the 80's, adapted for teh ATC and with the names of teh unit OC dropped in. I'm sure it must be some fairly old army song, certainly WWII if not earlier. I can imagine that it scans quite well with "Monty" as teh named commander. Anyway, this was our ATC version. Why don't you join? Why don't you join? Why don't you join old B_____'s Squadron? Up at six o'clock Twice around the block And there's Old B_____ with his hand around his cock. Why don't you join? Why don't you join? Why don't you join old B_____'s Squadron? Sitting on the grass, Polishing the brass and there's old B_____ with his fingers up his arse Etc etc... Any ideas? I tried googling it but just got a load of republican bollocks - though it does seem to be based on the same song.
