The ticket for my first concert, Kiss with Uriah Heep in February of 1977 was a whopping $7.50. A little bit of inflation from 1975 with two better bands as the openers for the ‘75 show. I think I paid about 125.00 per for Rush a couple of years ago on the R40 tour.
The R40 tour, I would’ve gladly paid for. Tried to get tics, but was a no-go.
Now that I remember, I saw the same tour in January 77 in Denver. Remember that the crowd was trying to get as close to the stage as possible only to be stopped by the cops. The lead singer (Byron IIRC) asked the cops to let them right up to the stage. Good times! :-)
