Formed as a British blues band in 1967, the group became giants of mainstream rock when Stevie Nicks and Lindsey Buckingham joined the Mac Attack in the mid-70s. Yet, from the start, relationship issues plagued the band, which famously wrote about their romantic troubles on the 1977 mega-hit Rumours. Still, the band announced this month that it plans to reunite for new music and a new tour, with Nicks telling the L.A. Times, "This band never breaks up."
In their favor: None of the band members are currently romantically involved with each other.
