This concert from the Mac is essential for two reasons:  1) you get to hear/see the songs left off from the Dance CD and 2) it was probably the last time Christine McVie toured with the band.  Even if you aren't a fan of Christine's songs, her voice beautifully fills in the 3-part harmonies that made Fleetwood Mac so famous.  And those 3-part harmonies were sorely missed on FM's latest album and tour (Say You Will), as good as that record and tour were.
