Nearly thirty years ago I attended this concert featuring two of my all-time favorite artists on one bill. I seem to remember Bonnie Raitt opening but I can't find anything about it online, so maybe I made that up. This cost 190 Francs. Adjusted for inflation, this would be 43,31 euros. Or 45.75 USD. There is no way you could go to a concert of any of these artists at that price nowadays. Even C-level bands charge around 60 euros these days.
