Ian and Sylvia did a great recording with different lyrics from those above. I think theirs was based on floaters from Lomax recordings of Mississippi prison and work songs. The best thing they ever did IMO - it stands up wonderfully well. It is the first track on Ian and Sylvia 'The Complete Vanguard Studio Recordings'. It starts:

Well, if I had a-known the captain was lyin', darlin', darlin' (x2)
If I had a-known that the captain was lyin'
I wouldn't have gone to work till half past nine

Dave Van Ronk also recorded a version on his 'In The Tradition' with the Red Onion Jazz Band. The track, however, is a Van Ronk solo. See Stefan Wirz site for details. It begins:

Well, it's early in the morning, the morning, when I rise, well-a (X3)
I got an achin' (misery?), mama, in my right side
