What I should perhaps have mentioned earlier is that there are broadside versions going back to c1680 'The Seaman's Complaint' with 14 stanzas is in Roxburghe and Pepys. Then there's the 10 stanza version in Ashton's Real Sailor Songs 'The Sailor Deceived' printed by Bloomer of Birmingham in the early 19thc. Logan's 'Pedlar's Pack' has an 11 stanza version c1745 titled 'The Disappointed Sailor'.
The Madden Collection has a broadside without imprint containing the first and fifth stanzas of the general stock followed by 5 new stanzas, titled 'The True-hearted Sailor'.

English oral versions tend to be somewhat fragmentary in comparison with these. Scots and American versions have fared a little better averaging out at about 9 stanzas.
