I saw the film two days ago in the Hyde Park Picture House in Leeds (UK). They say it's the only authentic 1940 s movie tetahre in the UK. It was a morning performance and on the website it was tagged BOYB . I reckoned this was sort of loop device for the hard of hearing. I asked the guy at the ticket desk, he told me it stood for Bring your own baby ! Yes the audience of only 12 were all young mommas with the kids at their breasts! Despite the distraction I thought the movie was beautiful to watch and one of Woody's best.
