I have loved Rush’s show since 1990 (a lot funnier then with fewer apocalyptics) but his personal plugs for his sponsors make me shout,
“Rush! Stick to the issues!!”
When you hear paper rustling it’s a tipoff that he’s about to read ad copy.
When there’s a brief silence and the words ‘Y’know folks...’ it’s another tipoff that he’s about to read ad copy.
I make no apologies for being a bit of an amateur audio engineer even I apologize for being a bit geeky and obsessive but I’ve taken to recording the RL show and cutting it down after (no need for podcast subscription either). I take special pleasure in nuking the Paul Harvey-style plugs lasting 2-3 minutes.
