Chuck Berry’s final album tops off legacy as rock pioneer

Chuck Berry -- early architect of the sound, attitude and raw power of rock 'n' roll -- died this year, but his music is getting a second life. A new album called "Chuck," his first since 1979, was announced in the months before his death on his 90th birthday, and charts his life as a kind of autobiographical epitaph. Jeffrey Brown talks with Berry's son and grandson about his legacy.
