I missed Zeppelin in Indy in 77. Saw the Who in Rupp Arena, and that’s my Rock religious experience. Zeppelin was ready to tour in 80, and I was definitely NOT going to miss it, but alas...
If they toured again, I would go.
The ‘77 show in Indy was pretty good. Although they ticked some people when they refused to play Whole Lotta Love, saying “we’re not into that s**t” anymore. But they did play Dazed and Confused which was the main song I wanted to hear, so I was happy.
