Daniel, I remember Don Brown from those days too, and he's one of the most knowledgeable people around when it comes to Peter Green & Fleetwood Mac recordings. And I owe him a big thank-you for helping to get me started trading Fleetwood Mac live shows, back in those "Views For Greeny" days.
Don, hope to see you join in the discussions here - it would be great to have your input on the Ledge boards.
