I will not post a link, because I don't want the horror and pain you'd experience on my conscience (also, I don't want to get sued), but the very worst song is a Swedish song called "I Et Rosa Helikopter" (possibly spelled wrong, I'm Norwegian, not Swedish), directly translated "In A Pink Helicopter". The name itself is quite a good hint to stay away from it. And before anyone even thinks this: no. It's not in the same league as Yellow Submarine. It's not even the same medium, because I really don't want to call Pink Helicopter music. I loathe it.

Anyways, I actually found a use for it a couple of years ago. I was working in a bar where there was a jazz jam one evening, which was really nice, but then a problem occurred: the players refused to stop. Service stopped (and they were made aware), they kept playing. Fair enough; according to Norwegian law, you can only tell people to leave the bar a minimum of thirty minutes after service has closed. The thirty minutes passed, while a colleague and I cleaned up, they kept playing. All lights were turned on by now, a definite hint. The last guests where told to leave, as we were closing up, they were told, but kept playing. As hopefully everyone will realize, packing down instruments takes a bit of time, and I wanted to get home, because it was now over three AM. So finally I turned the not inconsiderable stereo on, went on youtube on the computer connected to it, and found the so-called "song" I've described above. I think the jazz-guys still hold the World's record for combined quick-packing of instruments and the hundred meter dash...
