Happy 85th birthday to Chuck Berry, one of the greatest performers and songwriters ever. One of the best things about Berry's songs is the ease of the rhymes. No doubt he worked very hard to write the lyrics, but every line comes out as though that's what Chuck was going to say anyway, and it just happened to rhyme with the previous line. Berry's no saint. He's been on the wrong side of the law more than once. But he created perhaps the most glorious American music that has ever been heard.
