In January 2017, I was in deep in wedding planning mode. We were trying to save money on a DJ and trying to make decisions on some truly mundane choices. Should “Don’t Stop Believing” be at the beginning to get people on the dance floor or at the end as a final send off? Who can I trust to operate an iPhone to play “Concerning Hobbits” as my fiancée walks down the aisle, who will know how to fade out the volume at the correct time?
