McVie joined the band in 1970 after marrying the group's bassist, John McVie. She continued on with the group for the next 28 years as a principle songwriter, vocalist and keyboardist.
McVie wrote some of the act's biggest Billboard Hot 100 chart hits, including "Say You Love Me" (No. 11 peak, 1976), "Don't Stop" (No. 3, 1977), "You Make Loving Fun" (No. 9, 1977), "Hold Me" (No. 4, 1982), "Little Lies" (No. 4, 1987) and "Everywhere" (No. 14, 1988).
Fans of Fleetwood Mac have been teased with a possible McVie reunion since last September, when word first broke that McVie was going to rejoin her bandmates for a couple concerts in London. She appeared with the band -- for just one song each night -- on Sept. 25 and 27 at the O2 Arena, to sing "Don't Stop."
(Fleetwood Mac's 2013 tour incidentally, was the 17th biggest tour of 2013, according to Billboard Boxscore, grossing $62 million from 45 shows reported.)
Soon after guesting with the band at the O2, McVie told the Guardian that she would be "delighted" if the band were to "ask" her to play with them again. "But it hasn't happened, so we'll have to wait and see."
When Billboard caught up with Stevie Nicks late last year, while promoting her new "In Your Dreams" film and appearance on "American Horror Story: Coven," Nicks said "If Chris wants to come back to the band, I said to her, 'It's your band. I don't really think you have to ask. Because it's your band. McVie. Fleetwood Mac-vie? So, it all depends, Chris, on you. How you feel. Do you want to take this on again?'"
Finally, over the last weekend, the band's Mick Fleetwood reportedly told a crowd at a Maui, Hawaii show that McVie had indeed rejoined the group.
Undoubtedly, devotees of Fleetwood Mac are hoping for a new album from the famed "Rumours"-era lineup of the band, with singer/songwriters Nicks, McVie and Lindsey Buckingham. Together, the three were the principle writers of five studio albums from the group: "Fleetwood Mac" (released in 1975), "Rumours" (1977), "Tusk" (1979), "Mirage" (1982) and "Tango In the Night" (1987).
Following McVie's departure, Fleetwood Mac has released one new studio set, 2003's "Say You Will." The band also issued a four-song EP, "Extended Play," in 2013.
