Found - a 1935 theatre programme for Young England, a play by Walter Reynolds often cited as the worst play ever. Nevertheless it was a great success and some people saw it 20 times. We covered it pretty thoroughly at a posting at bibliophile site Bookride. We had found a copy of the book and catalogued it thus:

Quite scarce.'

He waited until the wits were through, then hissed: "Stymied!"
The programme includes "…a short letter from the author of Young England to his old friends, the theatre-going public."Continue reading
