I've been on a classic country kick since I saw Justin Townes Earle in concert two weeks ago. Here are the original tracks of the songs that he covered.
Mance Lipscomb - So Different Blues.mp3
Buy (e-music): Texas Blues Guitar (1994)
I can't find when this was originally recorded, but I am going to guess the early 1960s.
Lightnin' Hopkins - My Starter Won't Start This Morning.mp3
From: Lightnin'! (1967, out of print)
The Carter Family - Gold Watch and Chain.mp3
From: Gold Watch and Chain: Their Complete Victor Recordings - 1933-1934
(1998, out of print)
Buck Owens - Close Up the Honky Tonks.mp3
Buy: Together Again/My Heart Skips a Beat (1964, reissued 1995)
The Replacements - Can't Hardly Wait (alternate version).mp3
Buy: Pleased to Meet Me (1987, reissued 2008)
Yeah, yeah, I know this track isn't country, but too bad! The Replacements RULE!
Also, check out Justin Townes Earle on the Q (CBC Radio) podcast from March 8, 2010. He gives a really good interview, and plays "Poor Fool" with his band. The interview starts about 19-20 minutes into the podcast.
