Derek Welsman, who I remember as The Blind Movie Reviewer, has replaced Jason Barr on The Dean Blundell Show.
I'm giving credit to @Groked for tipping me off.
A few years ago, when I listened to more of The Dean Blundell Show than I do now, I remember thinking The Blind Movie Reviewer segments were actually pretty funny. In fact, they were often the funniest part of the show. Here he is banging into trees and singing about it.
The Dean Blundell Show is now Dean Blundell, Todd Shapiro, and Derek Welsman.
