Eric Clapton, Bonnie Raitt and James Taylor will be in the class of 2000 at Cleveland’s Rock and Roll Hall of Fame. They will be inducted — Clapton for the third time — on March 6 in New York, joined by Earth Wind & Fire, the Lovin’ Spoonful and the doo-wop group the Moonglows, the rock hall foundation said Tuesday. The foundation also will honor Nat “King” Cole and Billie Holiday as early influences on rock music, while Arista Records founder Clive Davis will be inducted in the non-performer category. Clapton, a rock and blues guitarist, was honored once as a member of the Yardbirds and once as a member of Cream. This time, he’s going in as a solo act. He’s the first to be inducted three times.
