Update: I am now running the open mic night along with a drummer, and things are progressing, but not how I expected!
There's varied mix of ages and tastes in the bar, as a result I'm always on my toes as to what we'll end up playing.
For example, Sunday night included songs by:
Adele, Neil Young, UB40, Christy Moore, Belinda Carlisle, The Levellers, Nirvana, Bob Dylan, Texas, John Holt, Bruce Springsteen, The Pogues, Elvis Presley, Fats Domino The Stone Roses, Bob Marley and a few original songs.
It's a very good way for me to discover music I wouldn't previously have countenanced, and learn new styles and meet (some) interesting people.
