Sounds suspiciously like the Police, "Every Breath You Take."

No, that's NOT the theme song to Mr. Ed. You might try checking out this link on Discogs:
Glen Hurlburt Trio – A Horse Of Course (Red Vinyl, Vinyl) - Discogs

The previous poster is correct, but the version is the one from the album "The London Chuck Berry Sessions."

This sounds like a very similar plot to Conway Twitty's "Don't Cry, Joni."

Would you believe 1948?

No possibility it's Elvis Costello's "Chemistry Class," is there?

My guess is "Where Were You when I Needed You?" by the Grass Roots.

This was well before Ray Stevens's time, but...
Love thy neighbor as thyself but leave his wife alone. (yorku.ca)

Could be a version of the Mexican song "Cielito Lindo."

Both Neil Young and Randy Newman wrote songs in the '70s titled "Old Man," but I don't remember the lyric "what about tomorrow" in either of them.

Sounds a little like "Why Do Fools Fall in Love," in the '50s by Frankie Lymon & the Teenagers, or in the '80s by Diana Ross.

Any chance it's this one? Not a hit, but one of the stations here in town played it a lot in the middle '60s.

"Takin' Care of Business" by Bachman Turner Overdrive comes close.
