That promotion is Insane Championship Wrestling. The BBC made a very well praised documentary on them last year, it was very entertaining and can be found on YouTube. In fact, here it is, definitely worth the watch. They do quite well for themselves and have a cult following of sorts in Scotland. In fact there is another BBC documentary in the works looking at the resurrection of professional wrestling in Britain and will be focusing on places like ICW, Preston City Wrestling, Southside, This is Progress and others who are selling out buildings consistently that can hold 2,000+ people.
I'd also recommend everyone watching Colt Cabana and Grado's entrances from a show they did. I've seen it in its entirety. Sabu getting a monster pop from a bunch of Scots was ridiculous.
As for McIntyre, his return made the Sun newspaper. Fair play to him for that. Nice to see him going back to his "roots" as The Drew Galloway. Used to watch him on shows here in Ireland under that name.
