OK Catters...I'm a professional Musician..have been for a good few years now..about ten..not that long really..anyway...always got paid for my gigs..I am about to venture to uncharted worlds..perform at a Fringe Festival in which performers "pass the hat". Its organized and all, but it's a busking atmosphere. How do I do it? I've never had to encourage people to py me before...assistance oh wise ones...
