I'm sorry I can't help you with your question regarding your father. The record label for the songs by Trio Dominio don't identify the vocalist, and we have no other way to know, without other sources.
Do you know if your father, Richard Deleon, was a member of this Mexican trio?

I am wanting to know if my dad, Richard Deleon, was singing on this recording? We have been looking for his recordings and it definitely sounds like him on there.
