Actually, try "about you" not "I love you"... it then goes on "the cows and chickens are going to the dickens! I love you a pushel and a peck, you bet your pretty neck I do. Doodle, doodle doodle, doodle doodle doodle doodle doodle doodle doo!!"It was from the stage version of Guys and Dolls and was sung by Miss Adelaide and her Hot Box Girls in the Hot Box Cabaret!
I could probably dig up the verses if you are interested.
