Madre justicia

I own the movie and i think that it is just great my husband & I love the movie but can you please tell me the person and name of the song that was playing in the bar when Chris met dusty.They say that this movie was based on a true story ,well where did the true story take place at and was Jack & Mary Brown the parent's real names? And in the real story did the Brown's really get custody of their granddaughter? And what year did this all take place? Is this movie out on DVD in the stores like at circuit city or best buys? Do you know if Patty Duke & Martin Sheen are going to make anymore movies together? I think that they act really good together.
