Yes, I've read it. He talks about how extremely young and inexperienced the band were when he first met them ("They barely knew how to turn on their own gear"). He seems very proud if his long association with them, and has a massive collection of memorabilia. He remembers certain shows vividly, for example the first time they played Madison Square Garden in 1984. He sat in with them during the recent recording sessions, to get an idea of where the shows might be heading, and calls the quality of the new record "just fantastic". He seems especially moved by the song Bono sings about his father (obviously SYCMIOYO, but he doesn't name it). He's excited about going on tour next year.
That's about it.
