I once led a staff to marry people on stage before KISS at Cheyenne Frontier Days, and boy did that take a lot of planning, for something that looked so informal (and hilarious, i.e. grooms with chest hair busting out of their black vests.)

Maybe Chris Martin had this figured out way better (after all, he's had waaay more stage time than I have!)  He flew with it moment by moment - totally screwed it up - but in the end, created some great entertainment!
