Playing music is not really susceptible to theory much. Circumstances affect it so much.
I'm inspired every time I see a role I'd like to play, an actor turn in a well crafted performance, a story I'd like to tell, direct or produce.
These songs are old friends I have entertained myself with when I'm washing the dishes, driving to the store and walking down the aisles. The ones that you sing when you're driving in the car and as a singer you always go back to them.
