Every town in America had at least one, two, or maybe three radio stations that played rock 24 hours a day. In England, we had a rock specialist on for two hours a week.
On the other hand in London you can get an audience that desires dance to go as far as it can go: they've seen the bricks of ideas built over a period so therefore there is an acceptance of what otherwise might seem out on a limb.
As much as my parents are part of Hollywood, I have no recollection of them giving me advice about it.
