Question about "Por Una Mujer Casada"

Does anyone know if the song "Por Una Mujer Casada" has 2 versions?

I'm familiar with the lyrics from Banda el Recodo's version but last night I heard a local banda play this song and I didn't recognize the lyrics. Musically, however, it was the exact same song! I've searched online but so far have only found one version.

?

Im only knows one version of this song, but many bands sing it

Lots of different groups sing this song. Depending on who sings it, they may change the lyrics slightly. You are probably listening to the same song with varied lyrics.
