A lot of years ago I heard a song in Spanish, but nowdaays I do not remember its name. I only remember some phrase (pronunciation, not spelling), here it is. If you know Spanish and or have ever heard something like that I would be glad to accept your help. Thanks!
Listening to your sentence, it seems to say "Soy un hombre muy honrado" (I am a very honest man), so the song you are looking for might be La canción del mariachi by Antonio Banderas and Los Lobos.
