Barbara; Significantly slower but not, I think, half. It's a bit weird to pick up - the intro verse is sung by Ewan (it's easy to remember how to spell this if you alway remember to mispronounce it as ee-wan) and his styling of it is very different from Lloyd's at the end, even though they are clearly intended to be the same tune. Even though MacColl wrote it, I far prefer Lloyd's interpretation. So as not to give the song three tunes, I try to sing both first & last a la Lloyd.

I think you have to hear the original to get this. And that difference may be why the last is not usually sung.

BTW, this is a very strong statement for me, personally, as I no qualms about describing MacColl as the world's greatest-ever ballad singer. (With the possible exception, according to Lawless, of Sandy Paton.)
