Ah but it isn't for us. It's for them. I have never once played Valerie without people rush up to dance. No matter how dead the gig, they get up. Similarly Sweet Child. Those opening notes are like crack to them.
I have passed through to a blissful place where I just love playing music for its own sake. It doesn't matter a bit to me what the song is.
I think it's age. I went through a couple of years convinced that I was washed up, couldn't get a gig for love nor money.
So when I landed a dep job playing stuff by bands I thought were the absolute pits, I didn't care.. Just so grateful to be making music with people. An epiphany if you like.
