@edgarblythe,
Good morning, edgar and WA2K.
That song by Marty Robbins from The Hanging Tree sent me to the archives, Texas, and I checked out the Isley Brothers and was surprised at all the great songs they had done. Amazing that they did Dylan's Lay Lady Lay. Thanks.
I was surprised also to find an interesting factor in Cooper's life was his friendship with Ernest Hemingway. I recall something about Cooper, when he knew he was dying, saying to Hemingway, "I'll get to the barn before you."
All of this info lead me to remember Errol Garner's great jazz song, Will You Still be Mine. It seems that there were funny lyrics(couldn't find 'em) saying, "when Gary Cooper's teeth don't stick"
So here is Errol and the lyrics will follow.

When lovers make no rendez-vous
To stroll along Fifth Avenue;
When this familiar world is through,
Will you still be mine?
When cabs don't drive around the park;
No windows light the summer dark;
When love has lost its secret spark,
Will you still be mine?
When moonlight on the Hudson's not romancy,
And spring no longer turns a young man's fancy
When glamour girls have lost their charms;
Sirens just mean false alarms;
When lovers heed no call to arms,
Will you still be mine?
When Julie Christie doesn't make me tingle;
When I can't sing in tune
Or make - a - single
When glamour girls have lost their charms
Sirens, they just mean false alarms;
When lovers heed no call to arms,
Will you still be mine?
Will you stil - will you still be mine?
Will you still be mine?
Will you still be mine?
Will you still - be - mine?
