Glen is a big U2 fan. He was at a recent concert in Boston and kept yelling for U2 to play People Get Ready. He knew that U2 used to play this song years ago, and when they did, they'd bring someone up on stage with them to play guitar. Bono heard him ask for the song, and then asked the crowd if anyone knew how to play it. Well, Glen did, because he'd been practicing.
So Glen gets invited up on stage and is given one of The Edge's Les Paul guitars. Here's the audio - Toursounds at U2Tours.com - U2 June 6, 2001 / Boston, MA.
HBO was filming the concert, so you might even get a chance to see Glen sometime in the future if he doesn't get left on the cutting room floor. Even if he does, he still has a memory that'll last a lifetime.
