I just love the John Williams performance that I found on YouTube which is titled "John Williams interpreta a Agustín Pío Barrios en vivo en programa televisivo (1976)" I would like to know if there is a CD of this particular recording. I haven't been able to find one but the original notes are in Spanish so I might be searching incorrectly.
I see this one in his discography but every performance is different.
