We surely miss his voice at a time like this.

when he mentioned Pocatello Idaho! Used to live there, he's got a good point.

American Falls and Lava Hot Springs

The early part does not sound like George.
Wrong cadence, the voice is off, the excitement not there.
If it is George, I understand why he buried the recording.
It simply doesn't sound like George.
Later on it is obviously George, but that early part, I don't think so.

I've been a Carlin Fan for years. Don't believe this is Carlin. Poster will have to come with some proof.

Or maybe the Youtube uploader... George gets started at the 5:40 mark.

Carlin combined whit and intellect to those things percieved to be crude and rude. I am using him as an influence in my work as a writer. Sexual purity or sexual "good taste" as it especially pertains to gender roles is the last bastion of ideas that needs to be comically assualted by someone with Carlin's comedic attitude.

"If you’ve not listened to Carlin recently, the new album, which comes out on Sept. 16 (Sirius XM subscribers can stream it Thursday at 4 p.m. ET on channel 400 and 7 p.m. ET on 94) will offer a few surprises. The first is that despite Carlin’s association with the counterculture of the ’60s and ’70s, he was performing envelope-pushing material even earlier: It begins with his home-recorded “Boston Rant,” made in 1957 when he was only 20."
