Cumberland Blues (Live At Oregon State University 1970) lyrics

I can't stay much longer, Melinda, the sun is getting high
I can't help you with your troubles, if you won't help with mine
I gotta get down, I gotta get down, I gotta get down to the mine

You keep me up just one more night, I can't sleep here no more
Little Ben Clock says quarter to eight, you kept me up 'til four
I gotta get down, I gotta get down, or I can't work there no more
[ Lyrics from: http://www.lyricsmode.com/lyrics/g/grateful_dead/cumberland_blues_live_at_oregon_state_university_1970.html ]
A lotta poor man make a five dollar bill, keep him happy all the time
Some other fella's makin' nothin' at all and you can hear him cry
"Can I go, buddy, can I go down take your shift at the mine?"

Gotta get down to the Cumberland mine
Gotta get down to the Cumberland mine
That's where I mainly spend my time
Make good money, five dollars a day
Made anymore, I might move away

Lotta poor man got the Cumberland blues, he can't win for losin'
Lotta poor man got to walk the line, just to pay his union dues
I don't know now, I just don't know if I'm goin' back again
I don't know now, I just don't know if I'm goin' back again
I don't know now, I just don't know if I'm goin' back again
