Maybe this is what it really means to be a singer-songwriter. Long after a car crash wrecked his face and his career as an R&B star, Percy Mayfield wrote. Listen, if only just to the names of the songs: “Memory Pain”; “Nightless Lover”; “Please Send Me Someone To Love”; “Hopeless”; “Lost Mind”; “The River’s Invitation”; “Louisiana”; “The Big Question”; “I Dare You”: “You Don’t Exist No More;” “Wasted Dream;” “Nightmare;” “The Voice Within;” “Life Is Suicide.”
