For all the people who say the beatles weren't necessarily rock? Wrong.
They were rock. They wrote for the stones, and created a demand for an Overseas sound in a (pre)dominantly driven US rock market. In turn allowing an opportunity for all British/English acts, who rarely, if ever had an impact on the U.S. market suddenly receive moderate radio exposure/potentially sales. In the following years of Beatles trail blazing, The Who, Cream, and many many others arrived upon their coattails. Years & years later, the likes of led zeppelin. All easily associated/intermingled with the U.S. rock market. How about English cinema? Do their movies go hand and hand with US releases? Not always. With this? People wanted the latest English band. The Beatles created this mystique.
Really, compare pre-Beatles rock, to post-Beatles.
The Beatles were kings since the days of the clubs. Some edges were rounded out for mass appeal/parents acceptance, but the mid to late 60's showed what these men were made of. Everyone forgets the cavern days, and how "rugged" (doubted) and short their U.S. appearance/trend would be.
In retrospect? Everybody's got a story now...
...stuart? eh, ignore and chop ringo in.
