Frank Sinatra, Sammy Davis Jr. and Tony Bennett were playing a charity gig and threw down a challenge that between them they could sing any song anyone suggested, or pay $100.000 to the charity,
little old man sticks up his hand and asks for ' Farmer Jack ' well none of them know it but before they pay up they ask him to sing it, so he starts off, Farmer Jack to a King,From Loneliness to a Wedding ring.
