My opinion of Kate Rusby? She reminds me of Matt Munro - every note in its place, every movement programmed, every gesture rehearsed, so that every audience gets the same "good show". I'm sure that is the explanation for the PA shenanigans described above, just as I'm sure she doesn't eat beans in case something spontaneous happens! There are some people who feel they have to work this way. and some who will push their abilities to the limit in public and chance dropping a clanger. I like watching the latter type of entertainment myself.
