Hey B Carter, MuchMusic is all about the kiddies now. They won't touch "adult" rock like the Hip any more.
MuchMoreMusic played the Silver Jet video all the time. In fact, I think it went to number one on their countdown. Unfortunately, MuchMoreMusic plays a lot of shite, so you've got to be patient if you're waiting for the latest Hip Video.
As for Vaccination Scar, I'm hearing it quite a bit on Edge102 in Toronto and HTZ 97.7 out of St. Catherines. It's a great tune that gets better every time I hear it. I too can't wait for the new disc this June. I listed the songs on the new disc on my site yesterday if you're interested.
