Leroy Carr. A traditional song which was a likely inspiration for The Train Song.. How long how long has that evenin' train been gone?. How long how long baby how long.. . Heard the whistle blowin' couldn't see the train. Way down in my heart I had an achin' pain.. How long How long how long.. . If I could holler like a mountain jack. I'd go up on the mountain and call my baby back.. . I went up on the mountain looked as far as I could see. The man had my woman and the blues had poor me.. . I can see the green grass growin' on the hill. But I ain't seen the green grass on a dollar bill.. . I'm goin' down to Georgia been up in Tennessee. So look me over baby last you'll see of me.. . The brook runs into the river river runs into the sea. If I don't run into my baby a train is goin' to run into me..
