Watched this film on a plane without any prior knowledge of its existence, and what a huge treat it was. Intelligently constructed by Davis Guggenheim - and frankly a great concept too - the three guitarists are very well chosen. We landed 20mins before the end of the show - hence my searching for the DVD - and I can only say that I was v distraught to be torn away from it. Great archive footage, great contemporary footage, genuine insights, contrasts, humour and needless to say, some not-half-bad music as well... HIGHLY recommend.
