David Harvey is a cowboy, working high in the Colorado Rockies; until four years ago he was with the Metropolitan Mounted Police and living at Parsons Green in London. Peter Vanson, also once with the London police, is still a policeman - on patrol in Watts, one of the most dangerous areas in the USA. A few hundred miles south in San Diego lives Vikram Khalsa - once Victor Briggs, lead guitarist of the Animals. He is now a Sikh and a plumber, and sings a different song. Ken Crutchlow, an East Ender who was labelled a "smart alec" at school, travelled round the world before settling in the wine country north of San Francisco, where he imports old London taxis and sells them as toys.
