That is factually inaccurate, the 60s British rock bands are well known to have stolen Black American music. Here's the basic story: late at night AM radio signals travel much farther and British teens would listen to Black American blues/roots/rock music and started imitating it. Eric Clapton & Jimmy Page are the worst offenders, as far as actual theft, but the influence was wide spread. The fact that white critics and audiences didn't account for this in their mythology concerning the British bands is a big sticking point for a lot of folks.
