Once upon a time William G. Scheele, who was the equipment/stage manager for The Band and Bob Dylan from 1969 to 1976 and a photographer whose work is on exhibit at the 14th Street Y’s Forward-sponsored December event, Bob Dylan and The Band: What Kind of Love Is this?, snapped a red-tinted picture of Dylan and The Band jamming with, of all people, Cher. Cher! It was an extremely arresting photograph — were they playing a wedding gig in Hell? — and, as the founder of the improvisational-writing website QuickMuse and the editor of JBooks, I thought it would make for a great session of improvisation. So I sent it to novelist Rick Moody, and asked him to improvise a written response.
