It's from LiveAid. Robert is going on about all the things he's doing and wouldn't have time for another 'Zep' reunion. Jimmy's getting visibly irritated. It's interesting to watch.
I love this shirt too. It gets forgotten about with the green satin shirt, planet shirt, and the famous one from '75. This one was partly see through. (John Lennon wore see through shirts too!) Oh, he's so perfect!
It was close to that. Jimmy was about the length it was end the last pictures of the Yardbirds at beginning of Zep. Since Robert's is curlier, that why I thought it may have been longer.
