I am belatedly responding to Leadfingers 'singing to the book' in particular. No names, no pack drill, so I shan't say where this happened, and I have quite forgotten who it was.

Reading from an electronic notebook with a small screen can be pretty crippling to a performance. The man in question was seated - not a good start - bent over this infernal machine. He was leaning over to see the content - presumably a small font and to frequently hit the page down button for the shallow screen. You may imagine what this did to his singing voice, breath control, phrasing and audience rapport.

As a memory, very funny. Rather a bore at the time, though.
