Recently, when clearing a dusty radio storeroom in London, staff uncovered a stack of boxes of BBC LPs labelled simply The Archers. They turned out to be 2,670 episodes of the serial from 40 years ago and hitherto believed lost, when Shula and Kenton were babies and Jennifer was a tempestuous teenager. Now Ambridge's adventures in the sexy, song-filled 1960s can be dusted off and restored for all to hear.
