I did ask PJ Harvey to come back – I wanted just one of her great iconic Stones guitar riffs. We have a relationship; I've endorsed her over the decades, but she chose not to respond to me. So I wrote her about how f***ing rude that was. Her manager tried to smooth things over, but it's not okay – she hasn’t played rock music in 100 years! Her first five albums are great; after that, she ventured into art space (though I do love The Last Living Rose, which feels like a John Donne poem with... WTF? A tuba?).
