Here's the song I used to sing as a child:
I'm looking over - a Four leaved clover, that I over looked before....
One is the Sunshine, the other is rain... 3rd is the Clover that grows in the lane.
No need explaining - the one remaining. It's somebody I adore..
I'm looking over a four leaved clover-that I over looked Before!
Thanks for finding it. Now I feel lucky :)
