Hey! Doc Watson sang that it was an apple!
(Of course, he also sang that Cain killed Abel with a spade - during a poker game. Hmmm)
Doc Watson:
‘I done had a vision;
I seen them pearly gates a’closin’
An’ I seen you sinners all outside.
You better make your decision,
An’ pray that you’ll be chosen, chosen,
‘It’ll be too late when you’ve laid down and died.’
