For nearly a quarter century now, if you're to walk into the Williamsburg bar Union Pool on any given Monday, you'd be going to church. There you will find Reverend Vince Anderson, conducting a sweaty sermon in sound with his Love Choir. A musician and minister of love, Anderson can now add “movie star” to his resume: He is the subject of a moving and inspirational new documentary called “The Reverend” by Nick Canfield. Both of them are guests on the podcast this week in a conversation recorded live at Nitehawk Cinema in Prospect Park.
