Back to 31 Squadron.
Perhaps one of them (who may perchance read this) could put in the full (expurgated !) text of the Song ? I give you:
"Now we come for Demob - Spats 'n Bowler Hat,
Back to dear old Blighty - it's Goodbye to All That.
The bloomin' Yankees got the best.
The ruddy Conchies got the rest ! -
We're Right A-round the Corner,
We're Right A-round the Bend !"
