Thumbs up for that one Grant. Thanks for the tip. Listening to it now on Spotify while at my desk. Interesting to see Clapton and the guys from The Stones and Zeppelin on there. Has anyone watched Ken Burns' documentary The History of Rock and Roll? He highlights the strong influence of the Chicago blues sound on all of these guys in their early formative years - Yardbirds, Stones, Zeppelin. Great viewing! Highly recommended.
