Listen to Fleetwood Mac on iHeartRadio

The band's all back together, if only for just one or two nights. 

Fleetwood Mac took the stage at London's O2 Arena Wednesday with long-departed keyboardist Christine McVie in tow.  In a moment captured on amateur video, McVie, who left Fleetwood Mac in 1998, rejoined the band briefly Wednesday night to perform their classic hit "Don't Stop." 

It's been a long road back to the concert stage for McVie who has repeatedly turned down the band's request to rejoin them on various projects.  Fellow band member Stevie Nicks finally announced recently that Nicks would rejoin them briefly for two shows on their current tour. 

Fleetwood Mac is celebrating the 35th anniversary of their classic album Rumours this year.  The band also recently released their first new music since 2003 - a four-track EP titled Extended Play
