This is very interesting..Bob Copper, having published his first three books, had his heart set upon a new book which would have been about his quest to follow in Alfred Williams' footsteps and attempt to discover families and relatives of the singers he had collected. Bob had come across Williams books and admired his work greatly - this may have had something to do with the fact that he was an autodidact much like Bob himself, in any case he could sense a kindred spirit. To this end he made two exploratory visits to Wiltshire with his wife, and about which he was greatly encouraged. Sadly this intriguing project went no further, as by that time (the late 1970s) Bob's wife's health had deteriorated to such an extent that travel away from home became impossible until the time of her death in 1983. A real shame for a 'what-might-have-been'.
