The Intelligence Corps Field Security Police would have in a field day writing out the report of the whole proceedings of the Brians Trust set-up for the troops camp concert entertainment. Sim plays his beleagued camp padre role beautifully well, with his typist WRAC girl, persisting in asking the crucial question about marriage to its very extreme detail answer. She typed out the suitable questions for the BT, so in practice, had editorial control of the proceedings & the direction the show took.
For those that do not remember or never heard of the Brians Trust, it was a development from a WW II BBC radio programme, which had wide audience appeal.
George Cole who plays the soldier nervously offering his "vote of thanks" to the padre for his efforts in organising the show, at the end of the film, was by this time, the adopted Barnado boy son of Sim.
For some good innocent Ealing comedy of the era, then this will kill 90 mins for you.
