Annie Nightingale is an Icon of DJ'ing, she's like the cool grandparent that everyone wishes they had. She was the first DJ at BBC Radio 1 and is now the longest running DJ on the station. She can tell you stories about partying with the beatles and jimmy hendrix while pulling out a cutting edge breaks tune that's about to destroy dancefloors around the world, at least when some other DJ's get ahold of it.
