How Long Blues Songtext

How long baby how long has that evenin train been gone
It's been gone since that blood red sun went down

Thought I heard a whistle and I think I see a train
Deep in my heart there is an achin' pain
Said how long, how long baby how long?

Well look down them tracks and feelin so bad
Lost the best woman that a poor man ever had
How long, well how long baby how long?
