He [Chuck Berry] was arrogant, rude. When he liked to turn it on, he could be most charming, but often he couldn't be bothered. First and last, he was amazingly mean.

There's an authenticated story about him that, on his first British tour, he used to study the evening paper nightly and check to see if there had been any fluctuation in rates of exchange. If there was any deviation in his favour, no matter how small, he'd demand payment in cash before he went on. On one night, this supplement came to 2s. 3 1/2d.

Still, all of this is irrelevant when you hear his records again.
