Lyric discussion by Anarchitect 

Seems like Portishead are fans of Steve Martin's 1979 movie, "The Jerk". In it, Martin and Bernadette Peters sing a rendition of "Tonight You Belong to Me" that features a ukulele arrangement. Check it out -- the resemblance to "Deep Waters" is pretty easy to see.

Somehow, though, I imagine the Portishead crew would just give you a sly wink if you asked them about it.
