I came across a description of this tango song in Brian Winter's book Long After Midnight at the Niño Bien, but only just got around to looking it up. It would make a great anthem for Theresa May's England.

Written by Enrique Santos Discépolo in 1935. I think it was first sung by Julio Sosa, whose film performance in this clip is a great piece of dramatic song delivery - unlike Gardel, who was compulsively charming, Sosa threatens to punch you in the face straight through the screen. It's like a scene out of the best Hollywood cinema of the era.

Lyrics here, with literal translation. It would be nice to have a singable English-language version but those extraordinary tonguetwisters would be a bugger to do in any other language. Somebody like Ian Dury might have pulled it off.
