I didn't find Lola's book to be boring, some of the stories in there (if true) are quite funny, but I suppose from the point of view of a band member, some of the anecdotes she tells could be a little embarrassing.
The problem is I'm never quite sure what to believe, she focuses quite alot on some of the insecurities and hang-ups of each member (Bono mainly), but in the main they're all pretty trivial. She only travelled with the band during the JT tour so we're going back a long way. The guys were still young and were trying to adapt to the sudden and intense pressure of massive stardom as well as trying to figure out who they were as people, so its only natural that they'd be a little neurotic.
Overall the books interesting for revealing the kind of relationship the 4 of them had with each other during this era, some days they apparently hardly spoke at all before going on stage, but that you'd never realise it from the kind of performances they gave. Its also informative for how analytical they are about there own live shows, about why one gig was electric and another failed to catch fire, they go over the set-list, the audience, the acoustics of the stadium, not a stone was left unturned in order to try and recapture that magic every single night.
She does tell a lovely story about the band meeting a female fan one night after a show who told them that she was an accomplished piano player and that she often played U2 songs on it. Holding her to her word the band all went back to her house where she proceeded to play and sing a very moving version of WOWY. Apparently half way through Bono joined in with her which prompted everyone into a big singalong.
I take all these stories with a pinch of salt but I'd like to think this one actually happened.
