Thirty-five years after his first album, Robert Cray is trying to figure out where all that time went."It seems like everything's gone by so quickly," says Cray, 61, who brings his band to town on Tuesday, March 10, at the Royal Oak Music Theatre. He and longtime bassist and musical partner Richard Cousins recently visited their former tour manager, which turned into a trip down memory lane to the 1980 release of the "Who's Been Talkin'?" album that launched Cray's career as a guitarist, singer, songwriter and band leader.
