In 1976 I saw them at Knebworth (spent 2 nights sleeping in a plastic bin bag under the eaves of some friends tent!!), brilliant gig, they made the Rolling Stones look tame, so I had to get it - not sure what the picture quality will be like or the surround mix for that matter.
Anyway it arrived this morning Lynyrd Skynyrd: Live at Knebworth '76 | DVD | Free shipping over £20 | HMV Store
turns out there is also a Blu-Ray version for a £1 more which I didn't spot! Lynyrd Skynyrd: Live at Knebworth '76 | Blu-ray | Free shipping over £20 | HMV Store
