I've decided to hand Sundays over to sombre music, and what better way to start than with Szomorú Vasárnap, or Gloomy Sunday? This song, written by Hungarian Rezső Seress in 1933 was reputed to be so gloomy that lots of people topped themselves after listening to it.
This was of course nonsense, though it was an excellent marketing ploy. Though there's no denying both tune and lyrics are incredibly sad (any song that ends on "The world has ended" is not going to be laugh-a-minute).
Szomorú Vasárnap has been covered by lots of different performers - including the dreadful Goth band Christian Death - but the most famous version is probably Billie Holiday's. You can watch it here.
If you really want a copy, I'd suggest plumping for one of the albums below. Just don't listen to them when your cat has just died and you've got a half bottle of Scotch coursing through your veins.
Note: I'm assuming the track is on the Billie Holiday set. Even if it's not, 10 CDs for well under a tenner is still a bargain.
