I'm not sure what's worse, trying to remember a song that you haven't played for over a year, or trying to work out a new song that you've never played.
I definitely play for fun. I don’t get an awful lot out of going over the same sections repeatedly whilst trying to work out what’s going on, especially when it’s buried in a horrible mix. I got to the end of the set in the end. It’s surprising how much comes back with ‘muscle memory’.
