I found some exciting news regarding the Rumours re-release boxed set from a very reliable music website,
http://www.directcurrentmusic.com/. According to direct, the boxed set will have 4 discs, which means that it will contain ALOT of material! Check out the excerpt:
More than forty years after Santana nicked "Black Magic Woman" from the original, blues-directed Fleetwood Mac, Mick Fleetwood is back with a new live version of that track and many others on Blue Again, a live album he recorded and released last year in Europe with The Mick Fleetwood Band. Rick Vito, a veteran blues player and one-time member of Fleetwood Mac, fronts the band on vocals and guitar. Blue Again drops stateside March 17. Also of interest is the pending release of both the Stevie Nicks live Live In Chicago/Soundstage Sessions CD and DVD hitting March 31 as well as the expanded 4-disc box set of Rumours (to be scheduled).
