Step away from the piano Lucy

In his autobiography, CHUCK BERRY reveals the origins for the song "ROLL OVER BEETHOVEN."
Berry says he wrote the song about his sister, Lucy, and her domination of the family piano in their youth. Berry wanted to pound out some rhythm and blues on the ivories, but Lucy kept him away with her classical pieces.
In doing so, Berry jokes (half jokes?) that Lucy delayed the advent of rock by 20 years.
I'm glad to hear that explanation for the song, because for years I have approached Berry's work as I approach the work of William Shakespeare: I cannot fathom how one individual could pen such a magnificent body of work.
Like Shakespeare, Berry makes the impossibly great seem so easy it beggars belief.
Consider this example from "Rock & Roll Music" -- "I've got no kick against modern jazz, unless they try to play it too darn fast; and change the beauty of the melody, until they sounded like a symphony."
Sure, Berry wrote about cars and girls (creating one of rock's most enduring templates in the process). He also could succinctly draw the distinction between musical generations while offering informed criticism as well, as demonstrated in the aforementioned line.
I have been listening to loads of Chuck Berry music recently. My marveling at his powers of communication never cease. Roll over William Shakespeare, and tell Ernest Hemingway the news.
