'Drying'-or going up on your lines-happens to the best of them. I once saw the elderly Sir John Gielgud in David Storey's Home lose his way during a long, important speech. No problem! Gielgud-always a good talker-veered off-course to deliver a fascinating, utterly irrelevant speech about the unpredictable English weather and the joys of gardening until, at length, he found his lines again. As he was playing a patient in a mental home, it didn't seem to make any difference what he said. Besides, it was Gielgud saying it.
