If I may, I'll quote my reply in a similar thread:
"A few songs off the top of my head:
Johnny Bush: Whiskey River, Undo the Right, City Lights, What a Way to Live
Guy Clark: LA Freeway, Like Desperadoes Waiting for a Train, That Old Time Feeling
David Allan Coe: Would You Lay With Me (In a Field of Stone), Another Pretty Country Song, Piece of Wood and Steel, Longhaired Redneck, Living on the Run, Spotlight, Willie, Waylon and Me, Lately I've Been Thinking Too Much Lately, Human Emotions, Jack Daniels If You Please, Please Come to Boston
Merle Haggard: Branded Man, Green, Green Grass of Home, The Bottle Let Me Down, I Think I'll Stay Here and Drink, Stop The World and Let Me Off
Waylon Jennings: Lonesome On'ry and Mean, I've Been a Long Time Leaving (And I'll Be a Long Time Gone), Honky Tonk Heroes, Oklahoma Sunshine, Low Down Freedom
Kris Kristofferson: Billy Dee, The Pilgrim Chapter 33, Sunday Morning Coming Down, Good Christian Soldiers, The Law is for Protection of the People, Duvalier's Dream
Michael Martin Murphey: Geronimo's Cadillac, Cosmic Cobwoy, Backslider's Wine
Willie Nelson: Pick up the Tempo, Pretend I Never Happened, Night Life, Crazy, The Sound in your Mind, Uncloudy Day
Jerry Jeff Walker: Hill Country Rain, Up Against the Wall Redneck Mother, Gettin' By, London Homesick Blues
Townes van Zandt: For the Sake of the Song, Waitin' Around to Die, Be Here to Love Me, Tecumseh Valley, Our Mother the Mountain, I'll Be Here in the Morning, Tower Song, Pancho and Lefty, Nothin'
Townes van Zandt straddles the line between country and folk so I'm not sure I should include his material, but what the hell. The man is one of the finest song writers to ever live."
