This is a completely different version to the single or album release, perhaps an earlier version or a later re-recording with Richard Dudanski on drums, who knows? The rhythm track is different and Lydon's vocals are an alternate take too. Although the track starts abruptly mid-song it's still 4:50 long. This take has more dub elements than the known version, beginning with drums only, then echoey guitar with additional synth thrown in, the bass line sets in after half a minute (Wobble even plays a few different notes towards the end of the song). Sometime after the middle of the song all the instruments, except bass and drums, drop out with the reverb looped and set in again after a while - great! It's sickening that the sound quality is so bad... This track is titled as 'Swan Lake' on some versions of the tape...

To me, this sounds like the same take of DD/SL that was used for the 3 studio versions in existence but with a different 4th mix by Wobble, one of his dubwise experimental mixes that caused so much uproar with JL & KL, I don't think this is an entirely different take.
