The ticket prices for concerts are a nail in Jesus hand. Unbelievers aren't going to pay to hear about Jesus because deep in their hearts they know they shouldn't have to. The gospel is free! -Keith Green
Then Keith quoted from Paul out of First Corinthians:
What then is my reward? That, when I preach the gospel, I may offer the gospel without charge, so as not to make full use of my rigth in the gospel.

That night Keith had around 8000 of his records ready to give away for free.
