NEW YORK (AP) – Fleetwood Mac is about to tour. But does that mean they will be on the road to support a new album?Not exactly is the best answer. Members of the group have been working on new music – with Stevie Nicks singing on tracks that Lindsey Buckingham, Mick Fleetwood and John McVie had worked on. But Nicks says she isn’t sure what is to become of the music. She says the way things are in the music world these day s , doing an album would be tough. But she says the group might release a couple of tracks here and there before deciding to share more songs. The Fleetwood Mac tour is set to start April 4 in Columbus, Ohio.
