Christine McVie is undoubtedly the longest-serving female band member of any of the enduring rock 'n' roll acts that emerged from the 1960s. While she has never fronted Fleetwood Mac, preferring to align herself with 'the boys' in the rhythm section whom she first joined 50 years ago, Christine is their most successful singer-songwriter. Her hits include 'Over My Head', 'Don't Stop' and 'Everywhere'.
