UNIVERSITY CITY, MO. (AP).- The image is timeless Americana: Chuck Berry hunched over, ready to launch into his famous Duck Walk, picking his Gibson guitar and wailing a song. It’s the image captured in the statue of the man considered by many to be the father of rock and roll, dedicated Friday in the University City Loop area of suburban St. Louis. Berry, now 84, still performs monthly at Blueberry Hill, a club and restaurant across the street from the new statue. He spoke only briefly at the dedication ceremony on a sweltering day as hundreds paid tribute to the St. Louis native. “I don’t know how to speak I can sing a little bit,” Berry, wearing his signature captain’s hat and bolo tie, said after thanking people for braving the heat to come out. “I’m going to say thank you again and I love you all.” Other legends of rock paid tribute to the man whose many hits included “Johnny B. Goode,” ”Sweet Little Sixteen,”
