1981 - Atlanta paid $40 each for Willie Nelson tickets, face value was $20 each, good value IMO. This was Willie’s ‘big band’ era when he had about 10 people on stage, including two drummers. He opened and closed with ‘Whiskey River’ and at the end a huge Confederate flag dropped down behind the stage. Jimmy and Rosalyn were on the side stage and came out and sang on the encore of ‘Will The Circle Be Unbroken’, in front of the Stars and Bars. Different times
The most I ever paid for concert tickets was $25 for Michael Jackson's "Thriller" tour (AKA The Jackson Victory Tour). He was touring football stadiums.
In 1984, that was about twice what a typical concert ticket cost by a leading band and it seemed crazy expensive.
