One of the founding members of Creedence Clearwater Revival, John Fogerty lost control of his own songs when the band broke up in the early 1970s. Now, after buying back rights to his Creedence catalog, Fogerty (who recently turned 80) has come back to his music, recording the album “Legacy.” He talks with Robert Costa about re-recording such classics as “Proud Mary,” “Bad Moon Rising” and “Fortunate Son.”
