I'm Looking Over A Four-Leaf Clover
Words by Mort Dixon, music by Harry Woods
Written in 1927 - popularized in 1948 by Art Mooney

I'm looking over a four-leaf clover
That I overlooked before.
One leaf is sunshine, the second is rain,
Third is the roses that grow in the lane.
No need explaining, the one remaining
Is somebody I adore.
I'm looking over a four-leaf clover
That I overlooked before
