At your local magazine/book shop you'll find the newest issue of NME, specially devoted to U2!!! This 146pg magazine is stuffed full of nothing but U2. From the early days to today.
Furthermore if you're into cycling like your announcer is, you'll find a nice mention of Bono and Lance Armstrong in the latest issue of Sports Illustrated (Sportsmen of the Year: Lance Armstrong).
Be well and go by them magazines.
