Bill Wilson, who died young, long claimed he wrote/co wrote much of Sultans of Swing.
an interesting discussion on the subject in the You Tube comments on Wilson doing SOS on You Tube.
Knophler has never acknowledged this, and tells a different tale.
i saw Dire Straits in concert twice.
the 2nd time, they had the usual half acre stage set up, but right before doing Sultans, the crew quickly brought out a maybe 4 piece drum kit which was set up front and center of the stage.
Knophler, the rhythm guitar, bass, stood right next to the drummer, and they did Sultans as if confined to an 8 x 8 bedroom they all could barely fit it together.
it was great, and gave a totally different vibe than the normal half acre stage set up.
they only did it for 1 song, but i wish they'd done the whole concert that way.
when MTV first hit Btown cable, they were doing a 1 hr concert show every fri or sat night.
this particular Dire Straits concert was one of the ones they did early on on MTV, (yes, my new beta vcr was rolling), and is the version on their Alchemy live double album.
a little bigger production and slightly better fidelity than the version MTIOTF posted imo, and with one of my favorite drummers who was a DS mainstay for a long time.
the Cliff Notes version guitar solo starts around the 6:50 mark.
