They may have gone their separate ways, but the chemistry was still there when they got together for a documentary.

``Fleetwood Mac: Classic Albums,'' was scheduled to air Tuesday on VH-1. The band, which won a Grammy in 1976 for its album ``Rumours,'' is planning a 45-day tour.

The reunion started when Lindsey Buckingham wanted help on a solo project and called on Mick Fleetwood. He brought in John McVie and before long, the band was back, including Stevie Nicks and McVie's ex-wife, Christine.

``The chemistry was so glaringly there,'' Fleetwood said Thursday. ``It was great - instantly, musically, fantastic.''

In the documentary, members recount the breakups and heartache that fueled their success more than 20 years ago.

All five of the band members at the time were in failing relationships, including between Buckingham and Nicks and the then-married McVies.

``Certainly the whole album `Rumours' is all about what the writers were going through,'' said Fleetwood, 55. ``They were literally singing songs to one another.''
