1: Can you play any instrument you want? 2: But I'm not a musician / I don't know how to play an instrument. 3: I can't improvise. 4: How do you know what key to play in? 5: How do you know when to stop playing? 6: What sort of people go? 7: Does everyone have to play? What if i change my mind? 8: Can you really just play anything you want? you can dance if you want to... 9: Doesn't it sound terrible? we never record free for all, so the only way to know how it sounds is to be there. but, if you decide to play, you will change the music - it will sound, at least partially, the way you want it to sound. it's impossible to know what free for all sounds like without your presence - maybe it does sound terrible. but whenever i go, i think it sounds great.
