From the interview:

“I actually wrote this to myself in my ukulele case on a Post-It: ‘Remember: perform it, have fun with it and put yourself out there.' Because that’s what John wants,” Murphy says.

“The biggest fear for me to overcome was to not be shy, to not be reserved, to go ‘Alright, this is it. Give it everything you’ve got. This is your moment.’ ”
