I had read about these guys, they've cited Lightfoot as an influence. You can hear a little of their version of Sundown at about 2:07.
"I must admit I was thankful they spared us the overcooked "The Crime Window" and instead capped the set with a "Southern Glass House" rendition bifurcated by a medley of covers-- including the Bee Gees' "I Started a Joke" and Gordon Lightfoot's "Sundown"-- on which the harmonizing was nothing less than glorious." -Pitchfork
