The 'Old Faithfuls' in our society give us a sense of context. They are the people of history, who are still alive. They tell of a time that has passed but which, through their life, is still within reach. When the old die out the young are forced to take their place.
John Peel was one of those 'Old Faithfuls.' He was one of the only constants in a scene that is dominated by the throw-away. As the longest running DJ on Radio 1 he flew in the face of this disposability of culture and the worship of youth.
Apparently he presented his shows as though he was talking to one individual. It really came across. Listening to his show was like being introduced to music by an old friend, who had been collecting music especially with you in mind.
Farewell old friend.
