Mysha: don't worry, Lloyd's imaginative amendments are still available in the Malcolm Douglas edition. There is a splendid line in "The Ship in Distress", for example:
"A full dressed ship like the sun a-glittering".
Who would want to leave it out, even though it would appear to be one of Bert Lloyd's flights of fancy? There does not appear to be any proven source for that nice bit out of "The Blacksmith" either: "with his good black billy cock on, decked with primroses". It is difficult to imagine that this is anything other than Lloyd creation either. Well, good for him, dishonest though he was in inserting them into traditional songs in a semi-scholastic book. But Malcolm Douglas has left them in, and pointed this out in his admirable notes.
