I like the song, too, but am not sure about the lyrics. It seems to me, as if he comes and goes like he wants to, and she is "leaning against his collar" and waits and waits.... hmm, if my husband would come only to leave again...well, I`m not sure if I like that (and that`s understated) ;-) ...
"Kiss me once and I'll be gone..." is a line from one of my all time favourite MK songs, The Long Highway, and I think it is also about restlessness and loyalty... I had problems first with the sentence itself, "Go, Love, if you're going".... but then I think I solved the "illogic" in it by reading the whole line,
"Go, Love, if you're going, I'll be here when you come back".
Do you think that's right?
About the collar: Very athmosperic, I really see a harbour and the weather is bad, rain or wind, and it is still dark (early in the morning), well, the music sounds this way, and he is maybe a soldier or sailor (or both), and they are about to bid farewell. So she leans into his collar a last time before he goes aboard ship....
