Music fans tend to divide into two camps at the mention of Fleetwood Mac. There are those who think of the multi-million-selling five-piece that formed in the mid-1970s and released Rumours, the biggest selling album of all time. But there are those who adopt a self-appointed 'cooler' stance, preferring the late-sixties blues band fronted by the virtuosic guitarist Peter Green. But that's not the whole story. Between May 1970, when Green left his own band to be replaced by the bass player's wife, to the beginning of 1975, when Lindsey Buckingham and Stevie Nicks joined Fleetwood Mac, there were five years of what can only be described as turmoil. One by one, talented musicians such as Jeremy Spencer, Danny Kirwan, Bob Weston and Bob Welch joined and left the band.

While it's impossible to ignore the skill and longevity such classic songs as 'Rhiannon' and 'Don't Stop' and albums Fleetwood Mac, Rumours and Tusk, there are an equal number of half-forgotten classic songs from the first half of the 1970s and many deep album cuts that have been overlooked. Here is the story of Fleetwood Mac in the 1970s - the music, the people, the tours, the rumours, the failures and the successes.
