I don't thing the 5am show is call-in. You can always listen to it at CKNW's audio vault.hdtvman said:Shell Busey was talking about this soundprooof drywall product on CKNW this week.
If you are an early riser, give him a call on his Saturday (5AM!) show on CKNW. It seems pricey but he said that it really works well.
Or you can go to Shell's HouseSmartCenter and search for "soundproofing". There's several FAQs on the topic.
