I Played My First Gig- here's what I learnt...

Two years ago I decided I wanted to learn how to play a musical instrument. Learning as an adult with no previous musical knowledge, I wasn't sure I'd ever be any good. Scroll forwards a couple of years and I've joined a ukulele band. I've just played my first gig with them (think village hall with tea and biscuits...)
I still may be on the musically inept side, but here's what I learnt from my first live performance.
