Up early, teaching half a day before I went to the gig.  Did a gig of Christmas songs they wanted.  Thing is, I'm not as familiar with these holiday tunes even though I practiced.
So, I missed more chords and lyrics than I care to admit....combo of being tired and maybe just not being ready as a solo gig.  
Christmas gigs, in the past, wife sang; I concentrated on playing.  
Crowd was very forgiving, but I was not happy with my performance.
