Jar jar - you are probably right -I am long out of practice (plus i can't sing

). I think over 50 the only option is expensive gifts
This turns out to be a very old poem from 1915- this explains the B&W video and period costumes
http://www.bobdylanroots.com/spanish.html"Of all the cowboy love songs which sang of sweethearts true and false, this touching literary ballad by the well-known western poet Charles Badger Clark, Jr., has enjoyed the most sustained popularity. Written under the title, "A Border Affair," the poem struck a responsive note in a sentimental age. Its story of true love thwarted by the barrier of "racial" differences... had wide appeal in a romantic age. And long after many another cowboy ballad had been consigned to the printed page, "A Border Affair" was sung and declaimed by cowboys out on the range. For there is a sentiment which appeals to us all in this bitter-sweet ballad of the rough-hewn cowpuncher who doesn't "look much like a lover" and the senorita who whispered, "Adios, mi corazón."
But it is easy to play(???) plus catchy, and just explain it is a story of love, separated by the Mexican Revolution, maybe it is O.K.
