Wonderful new video posted by Mark Zep on August 11, 2022 - in other words, on the anniversary of Led Zeppelin's appearance at Knebworth on August 11, 1979.
Beautiful dual acoustic performance of Roy Harper's Same old Rock. Nice to see Jimmy Page playing well and looking healthier in this one. The audience must have been stoked to see the pair of them together.
