Paul Simon must've heard "Let's Say Goodnight," the zydeco shuffle that Los Lobos recorded on their 1983 EP debut, "...And a Time to Dance," because he invited the band to the studio when he was recording "Graceland" in 1986. The result was the final song on "Graceland": "All Around the World or The Myth of Fingerprints." That's vintage Lobos, back when Louie Pérez was still playing drums. But what I didn't know is that there was a nasty battle over the songwriting credits. SImon has sole credit on the album, which the band argued against. Not sure what the legal result was, but you can't argue with what is a mighty fine song.
