Who knew? Pulitzer Prize-winning civil rights historian Taylor Branch (America In The King Years), left, is an ole rocker. He and two college buddies, who once sang as The Zookeepers, reunited for a Beatles cover CD called The Blue Album. I just heard it, and it's great sing-along fun. Branch, who lives in Baltimore, Bill Guy and John Yelverton sound like teens. This is the group's second CD. "If you ever need giddy fun or relief after a profound election, this is it," Branch writes.
