Earlier this year, on the second Saturday night in May, the Crazy Wisdom Tea Room was crowded by 8:00. It was Indian Music Night. (Indian Music Night # 95 to be exact, but more on that in a minute.) A quintet of musicians sat in chairs at the front of the room, their backs to the windows that look out on Main Street. John Churchville, the founder of Indian Music Night, was warming up on the tabla (the traditional Indian hand drums), while Dan Ripke picked out notes on his acoustic guitar.
