Well I am now forgetting words of songs I have known for years, so I sometimes have the words on a chair or a table nearby, in case I get lost. I may glance down at them, but I would never have them up on a music stand in front of me. A music stand is for music anyway, not words. The clue's in the name.
Worst incident I saw at a singaround was at the Yacht Club in Broadstairs, when Tom and Barbara Brown were running the evening. A lady said that her son didn't want to come, but he had prerecorded her accompaniment. She then turned on a tape recorder, and sang along to the disembodied accompaniment of her son, in absentia.
I were gobsmacked I were!
