Harry 'Bayou Riley' Nilsson's "1941" is an autobiographical chantey originally released on Nilsson's Pandemonium Shadow Show album.
Well in 1941 a happy father had a son
And by 1944 t' father walked right out t' door
And in '45 t' mom and son were still alive
But who could tell in '46 if t' two were t' survive?
