There was a time Zeppelin collectors had NO pro shots. The Earls Court 75 shows, Knebworth 79 shows and the Seattle 77 video were Holy Grails. Now - anyone with an internet connection can get them
I recommend using the search term “Badgeholder Blues” on some of the better Zep forums.
I’m just sayin’...
So I Googled "Badgeholder Blues" and found my self down a rabbit hole last night. It led me to the official Zep web page and I found the page linked to the 77 show I attended in Detroit, but couldn't hear it clearly due to the echo in the massive Pontiac Silveradome. There were several reviews and recollections of that night, many which brought back some fond memories. However the most rewarding of all was finding a link to a YouTube containing the audio of the entire show. It was recommended to listen to it with 'bootleg ears', and today I did just that. The quality was much better than I expected for an almost 44 year old recording. And now I can finally say I heard the concert as it was intended to be heard. And it was an amazing show performance wise, with many online placing it in the top ten of the entire tour. And FYI, this Detroit show is aka Hot Rods in Pontiac.
