PJ Harvey: why does that surprise you? Admittedly, we've never seen her perfom live before but we were invited and we could have turned down the invitation. As it happens, we enjoyed it and ourselves immensely. The style of her presentation bore similarities to a concert by "Mr Bob": stage in darkness between songs; no words for the audience between songs; a simple "Thank you" and band introductions at the end. Mostly, it was built around LET ENGLAND SHAKE but she also performed some older songs (such as "Down By the Water", which I always call "the blue-eyed girl" song, and "The Desperate Kingdom of Love").
I have not really followed her career closely but I was passed a couple of her CDs by a friend in the music business in continental Europe. I must get them out and play them again some time. I was first aware of her about 20 years ago when she did a Bob Dylan cover ("Highway 61 Revisited") and, as a result of that, became friendly with someone who does follow her career closely.
The temporal proximity of Michael Sheen's "Hamlet" performance was a coincidence. We had planned to attend that anyway. In fact, as it was a preview performance (regular performances started this week, I think), we had to book tickets long ago. Previews are also a bit cheaper than the regular shows, so it is worth the effort and the wait..
Sinatra: the bit in parentheses about "Mr Frank" was merely to avoid misunderstanding on anyone's part.
