I found another song that has the same melody as "I Left My Love" which was written in 1959 (not quite 50 years Sol, but it seems that long ago to me also).

The other song with the same melodic structure is "A Cane and A High Starch Collar" sung by Elvis Presley in the 1960 film "Flaming Star". This song was written by Sid Tepper & Roy C. Bennett in 1960.

The chorus or bridge melodies are exactly the same and I first noticed the similarities when I heard the first phrase starting with "Hi-Lo" from this song's bridge. The first phrase of the bridge of "I Left My Love" starts with Heigh-O.

A CANE AND A HIGH STARCHED COLLAR

Cowboy, cowboy marry me
I'll bake you a cherry pie
Well thank you very kindly mam
But I'm too young to die

Hi-lo-do-si-dosy-do
Stay single and save a dollar
Come Saturday night I'll court a pretty girl
With a cane and a high starched collar

Cowboy if you'll marry me
I'll be your darling Jenny
Now why should I drink from just one well
When I can drink from twen'y

Hi-lo-do-si-dosy-do
Stay single and save a dollar
Come Saturday night I'll court a pretty girl
With a cane and a high starched collar

Cowboy, cowboy name the day
July 'd be nice I reckon
Gladly meet you at the church
July the 32nd

Hi-lo-do-si-dosy-do
Stay single and save a dollar
Come Saturday night I'll court a pretty girl
With a cane and a high starched collar

You sleep all day and spoon all night
And eat your favorite chow
Then why should I get married mam
That's what I'm doing now

Hi-lo-do-si-dosy-do
Stay single and save a dollar
Come Saturday night I'll court a pretty girl
With a cane and a high starched collar

The older I get the more I am finding that one melody is often used for more that one song, and sometimes many. Priority for this melody probably goes to songwriter Stan Jones. However, who knows whom he "borrowed" it from.
