FIRST OFF . . .

Add two new names to the long list of members of Fleetwood Mac. The veteran rock institution announced Tuesday that guitarists Rick Vito and Billy Burnette have come aboard, replacing Lindsey Buckingham, whose departure was announced earlier this month. “Lindsey knew we were going on the road and he wasn’t too keen on doing that, and we decided to go ahead with the tour,” group founder Mick Fleetwood said at a press conference at Le Bel Age hotel. (The big Mac’s U.S. tour begins Oct. 1, with a Los Angeles date to be scheduled sometime between Dec. 8 and 12.) In concert, Vito and Burnette--both longtime members of Fleetwood’s on-the-side band the Zoo--will both do the vocals on Buckingham songs. While Stevie Nicks emphasized Tuesday that the group will still sound like Fleetwood Mac, Buckingham’s departure figures to be felt when the band records again. He was the acknowledged architect of the Mac’s lucrative ‘80s sound.
