That's from The Royal Albert Hall and was released on the DVD they put out about ten years ago. In my opinion the best official live video of Zeppelin released. Second best is the Danish TV Special footage. Had both on bootleg video years before the official release. Robert Plant sounds about the best he ever did at this show. I believe We're Gonna Groove was taken from this show and overdubbed and released on Coda (as well as the Coda version of I Can't Quit You). Catalinbread released a pedal based on Jimmy's tone from this show (RAH).
