IRISH SONGS – IN HONOUR OF ST. PATRICK’S DAY
5. I’M LOOKING OVER A FOUR-LEAF CLOVER – 1927
Written by Bronxeville, New York composer Mort Dixon, whose first hit was That Old Gang of Mine in 1923, followed by Bye Bye Blackbird in 1926.
Music composed by Harry M. Woods (a Tin Pan Alley Songwriter of the depression years), of Boston, Mass. Woods also wrote these hit songs: When the Red, Red Robin and Side By Side, among others.
The original hit recordings of the song were made in 1927, but the song was revived in 1948 by several artists, most notably Art Mooney, whose recording topped the charts for 18 weeks. (First result to come up on Youtube)
Ukulele-playing television personality Arthur Godfrey also had a hit recording of this 
song during the same year, topping the North American charts at #14. It is likely that no other single person has been directly responsible for the sale of as many ukuleles as Arthur Godfrey, an enormously popular television star of the 1950’s and 60’s.

This song was created after WWI and during the Roaring Twenties. Musically it’s called a Chorus Song. Lyrically it’s an Appreciation Song. Times were tough during the first Word War, but we survived and are having fun in the 1920’s! As the U.S. entered the second World War in 1941, it was a very popular big band song on the Eastern coast, and became an Irish-American WWII tribute song which was played repeatedly in home-coming parades.
I’m Looking Over a Four-Leaf Clover This version is from Dr. Uke and we like to play it twice over. There is another version that has verses, and below is a video of the song as performed by Donny and Marie Osmond.
