Rick Beato's channel has a lot of great videos. Zep fans (particularly musicians) will appreciate his breakdowns of Ramble On: and Whole Lotta Love:

It seems like everything is on Youtube... Royston Ellis backed by Jimmy Page (unfortunately we don't see himJimmy). The low number of views makes me believe this hasn't widely been seen. Jimmy plays from 3:20 - 4:20.

Yardley's tour dates from Melody Maker, Apr 13, 68:

A few clippings from Melody Maker (second one mentions a Bonham solo) (July 6th, 13th and 20th, 1968). Also, re the Tim Rose appearance on Top Gear (July 1st, 1968), although Dougie Wright is listed as the drummer (source), that sure does sound like it could be Bonzo. Maybe it's just wishful thinking. Have a listen here. Track 1 - Roanoke: drumming with his hands (1:55) Track 2 - Foggy Mountain Breakdown On Rye With Mustard: multiple drum rolls (e.g. 4:34 & 5:00-5:20) Track 3 - I Guess It's Over: drum rolls throughout [triplets?] (e.g. 6:40, 7:00, 8:16, 8:20 ...) Track 4 - Long Haired Boy: multiple rolls throughout but harder to make out (e.g. 11:00)

Mark Lanegan’s new album Straight Songs of sorrow features JPJ on keyboards on Ballad of a Dying Rover. http://www.marklanegan.com https://www.youtube.com/watch?v=3alMP5Jj-YU

I have them as playing the Corn Exchange on the 23rd of May, and at the Tiles Club in London on the 26th.

You can hear the guitar come in at 1:50 and at 3:22. I agree that it's fairly straightforward. I wonder what the back story is.

So on March 4th, 68, was Bonzo playing with Tim Rose, or the Band of Joy, or both?

So I just saw Green Book tonight, and saw that Robert Plant had some input into the soundtrack: HOW ROBERT PLANT HELPED CURATE THE ‘GREEN BOOK’ SOUNDTRACK Robert Plant is partially responsible for the music found in Green Book, Peter Ferrelly's Academy Award-nominated movie about jazz pianist Don Shirley and his experiences with racism on tour in the early '60s. In a new interview, writer and director Peter Farrelly revealed that a dinner with Plant helped turn him on to the songs that were eventually used. "My wife's friend was going out with Robert Plant of all people, we went out to dinner and I picked his brain," Farrelly told Forbes. "I said, 'Robert, tell me some songs that you listened to in the late '50s and early '60s that nobody plays anymore. I want to hear the cool songs to you but that you haven't heard on the radio in 50 years.'" "It was an amazing night because I had just finished writing the script and he came to visit with his girlfriend, who was my wife's friend," he continued. "And my wife and her are both smokers, so they were outside smoking cigarettes and we were on YouTube and he was pulling up song after song after song and I was sitting there like a crazy student writing down all the stuff." Plant put his encyclopedic knowledge of American music to the test, playing Farrelly songs like "Pretty Lil' Thing" by Sonny Boy Williamson and "Goodbye, My Lover, Goodbye" by Robert Mosley. Its soundtrack, which combines some of Plant's recommendations with Kris Bowers' original score and one of Shirley's own recordings, has received more than a million streams to date. Farrelly added that using more obscure songs had a few benefits. "Number one is it didn't feel like Happy Days," he said, "like playing all the songs we've heard over and over. But also those songs were really inexpensive and I did not have a huge budget so I was able to come up with some sensational pop songs from the time that were long forgotten."

"Bob Spitz" author of The Beatles? Is that you? That was a great book.
