This Friday sees the theatrical release of CSNY: Deja Vu, a very different kind of band documentary. It follows Crosby, Stills, Nash and Young on their “Freedom of Speech” tour in 2006 and features a combination of performance footage combined with stories from and interactions with fans on the road.
