By Tom King We continue our look at the music of 50 years ago…. Those of a certain age remember the wonder of Woodstock. Even if you weren’t there you know about the rain & mud…about the massive crowds and traffic jams…and the list of acts that reads like a who’s who of 60’s rock. The Dead & The Airplane, Hendrix & The Who, CSNY, Sly Stone and CCR, Santana and the Keef Hartley band…..wait…who?? Yes, the Keef Hartley Band played Woodstock although you might not have known it because their set never appeared on the LPs or the movie of the event.
