A sailor tells his true love "It is all for your sweet sake I am bound to cross the ocean." Her mother and father are against them but she will not turn against him. He promises to be true. They kiss and part; she wishes him well.
Roud lumps this with Laws O30, "Jimmy and his Own True Love." It's a difficult question, since the only field collection of O30 in Laws is from Mackenzie. But the Mackenzie version revolves around the giving of the ring. Until and unless I see the broadsides Laws cites, I'm keeping them separate.
In addition, it appears that at least one version of this song is entitled "Lisbon," a title usually reserved for "William and Nancy (I) (Lisbon; Men's Clothing I'll Put On I)" [Laws N8]. Laws did not know any of the Newfoundland collections cited for this song. Again, we separate, because this has no cross-dressing theme or promise by the girl to come with him. - RBW
