Thank you all for your encouraging words! I realize that there's safety in numbers, so a solo open mic will be a whole new challenge when the time is right. There were four in our class, but only three performed. The fourth person said she would come to support us, but wouldn't play. I actually brought an extra uke in case she changed her mind, but she never turned up. I'm guessing that maybe it was because the scheduling email that the school sent had an incorrect address for Off Broadway, the place where we played. The street address is 3509, but the email said 359, so if Susan just went by that, she'd never have found the place.
I took my Pono all-rosewood tenor (one of only eight made; they were the subject of a feverish thread last April and May). I'm glad I didn't take The McLaren because I somehow banged the Pono on something when I was going onstage (big steps for an older person! [who, me?]) and it now has its first ding. I was sad about that, but I quickly came to see it as a battle scar and a memento of my first public performance.
