One obvious difference between the earlier groups and the later ones was in their social backgrounds. Earlier American groups, having grown up together, were all of the same social origin and colour. What is more, they had usually sung together, and socialised together, before they formed up as a group. This is also true of most of the earlier British boy groups. The later groups, on the other hand, were deliberately chosen for variety. This was done so that all sections of the audience would have at least one member they could identify with. They had not sung together, or maybe met each other, until their PR manager introduced them.
