Really? I didn't know this. I checked YouTube and I found this:

It is the same melody, but totally different words.

Still... for me... I love "I did it My Way"... the version by Paul Anka

Thank you for showing me this.

There is an interesting story... "It's Impossible" made famous by Perry Como, was written by an American composer. And then, Armando Manzanero, a great Mexican composer of many beautiful songs, came out with "Somos Novios." The same melody, but totally different words. One sued the other, and they reached a happy agreement: from then on, they would BOTH be known as the co-composers. Of course, the Mexican composer paid a huge lump sum to the American composer.

Also... George Harrison was sued and LOST for taking the melody of "My Sweet Lord" from another song, "He's So Fine" sung by The Chiffons and composed by Ronald Mack.

Here's an interesting mix of "My Sweet Lord" and "He's so Fine"
