Their biggest selling album for the week was the 1988 release "Greatest Hits," which re-entered the Billboard 200 at No. 200. On the Top Pop Catalog Albums chart, it returned to the chart at No. 32.

Billboard first officially confirmed McVie rejoining Fleetwood Mac in January, by way of the act's publicist, Liz Rosenberg.
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).
The current incarnation of the group -- with Lindsey Buckingham, Mick Fleetwood, John McVie, Christine McVie and Stevie Nicks -- will kick off the On With the Show concert tour on Sept. 20, 2014. It will be the first time the five have toured together since 1998.
