How the Sony Walkman ad was made

Here's a short film about how the Sony Walkman ad (with all the musicians playing one note each) was made - at Alexander Palace in London in October. You might want to skip between 3:25 and 3:50 to avoid the marketing execs explaining how the ad embodies the maverick nature of some crap Mp3 players, but otherwise it's great. Were any of you there? The dude with the Moog Source at the front looks like an MT reader to me... (Thanks Fab)
