When hiring musicians to play as you walk down the aisle it should become normal practice to see if they marched in a college band. Here's why this should be considered. First of all, they know what it is like to play in high pressure situations. Second, they are familiar with playing front of large crowds and third they have already been through a pretty intense audition process in their life which would guarantee to you that they ACTUALLY KNOW HOW TO PLAY THEIR INSTRUMENT!
This couple may not have done, well, any of those things this past November. At least he was committed to his performance and never gave up! RIGHT!?! Oof.
