U2 - Live from My Office
I've known about U2's rooftop gig for weeks. The secret was public by Wednesday but until then we'd been pretending that the "big Irish band" who were going to perform on top of Broadcasting House were B*Witched. Few were convinced.
The Music Interactive team's office in Portland Place has the best view of U2's open air 8th floor stage so it's no surprise that we've been overrun today by a TV crew. There are wires stuffed behind the radiator next to my desk and Health and Safety have allowed the windows to be fully open for the first time that I can recall so that two TV cameras can poke out and film the band.
The mid-afternoon lull was broken at 4pm when Bono and The Edge stepped out onto the Broadcasting House balcony. A crowd on Regent Street, all hoping that their camera phones could capture the moment, let out an enormous cheer.
4pm: Bono gives the gathering crowd a wave from the Broadcasting House balcony
By the time it had got dark the crash barriers had gone up along Regent Street and a massive crowd had gathered. It was interesting overhearing their voices which ranged from "What's going on here?" to "I've known about this for days."
Before the gig started at 6.45pm the office was full of faces I didn't recognise and even some children. I should have sold tickets.
My colleagues Tim and James, who produce the websites for our major music events like Glastonbury and the Electric Proms, have been holed up in a meeting room "closed to unauthorised staff" making sure all of the content from today is published as soon as possible.
You can now watch all of this morning's Live Lounge set from the Radio Theatre as well as gems we've found in the BBC archive. My favourite is the clip from a 1981 episode of Top of the Pops which you need to watch for both Dave Lee Travis' 'comical' outfit and some special effects possibly created on a Commodore 64.
Later tonight you'll be able to watch all of U2's performance from the roof of Broadcasting House on the website and tomorrow highlights from all of today's fun and games on the TV via the red button.
Do leave a comment and tell us what you think of U2 at the BBC.
