VOX POP: HOW DARTFORD POWERED THE BRITISH BEAT BOOM

In the early 1960s British pop groups conquered the world. But as the Beatles, the Stones, the Shadows, the Dave Clark Five, the Yardbirds and many others took to the stage they had one thing in common - they shared the platform with Vox amplifiers. Some of the nation's top professional musicians including Queen's Brian May and Bruce Welch of the Shadows, along with the factory workers of the time, recount the story of how an unlikely small company in unglamorous Dartford hit the big time and defined the sound of the 60s in Britain.
