Imagine listening various new bands on soundclouds and then the SOS demo starts playing... 
Yes, but at the same time, if not Mark, probably by this time somebody would rediscover this kind of sound already, though even some pre-Dire Straits JJ Cale songs sounds like MK played on it, I even had a little collection of JJ Cale songs with most "MK" playing, but I lost it somewhere. My point is, Sultans could only emerge in this time and from that band, so as always, it's a great example of some major luck.
