Gotcha on that one!
I went technical "OD " (Baptist) at Sleaford Tech in 1968 , along with all the other members of 99 "A" squadron Hut 139. Six guys all with a different OD cause ("wot a coincidence")
"Left right, left right" down to tea and biscuits with Padre Silvanus on a Sunday morning, instead of massed devotion (?) with the rest of the herd.
Actually he spoke bloody good sense, which I've never forgotten.
