Ahhh, Siobhan-from-Bananarama's later career. God, they showed that video incessantly on TOTP; against some complaints, I believe, because of the dying man vibe over teatime. I was never sure she was Death, exactly, rather than some alien killing machine, just because of the lyrics ("hope and pray that you make it safe back to your own world" etc). But I haven't watched it in twenty years, I should think. And expecting it to make more sense in retrospect might be optimistic.
