Last week, we checked out of the library a DVD of the pop singer Adele’s concert at The Royal Albert Hall in London. My kids like her songs, and so do I, when I’ve heard them. I also love the fact that she’s a working-class Londoner who has become a worldwide success on the basis of her extraordinary talent. She has seemed so likable in the few interviews I’ve seen with her on TV. This was a hard concert to get through with the kids, because Adele has a very foul mouth.
