"...There is no fairer way to decide..." Now, this seems unimaginative. Surely, especially given all the feedback and critique on this thread, you can come up with other factors besides price that should influence fairness in this transaction? We may decide that introducing other factors (like band loyalty or degree of enthusiasm for the show) is difficult, impractical, or threatens entrenched interests, but that's another issue. We can't let enthusiasm for the allocation properties of markets ("it's Pareto optimal!") bleed over into value judgements about the outcome ("...so we all agree it's most fair!").
