I'm Looking Over a Four Leaf Clover
The original hit recordings of the song were made in 1927 by Nick Lucas (#2), Ben Bernie (#3), and Jean Goldkette (#10). The song was revived in 1948 by several artists, most notably Art Mooney, whose recording topped the charts for 18 weeks. Other charting 1948 versions were made by Russ Morgan (#6), Alvino Rey (#6), The Three Suns (#10), The Uptown String Band (#11), and Arthur Godfrey (#14).
In modern times the song is perhaps most associated with Merrie Melodies cartoons, as it appeared in several of them, and a common tune played by the string bands in Philadelphia's Mummers Parade. The Sons of Ben, the official supporters' group of Major League Soccer's Philadelphia Union, have adopted the song as one of their chants, singing at every home match at the 20 minute, ten second mark, symbolic as the founding year of the Union.
