Greatest Secretly Recorded Rants?

Pete Townshend has a unenviable history of rants, this one is from 1971 at a show in Long Beach.

After the Buddy Rich bus tapes, there’s the infamous (at least to Chicago sport fandom) Lee Elia rant, where he’s just had enough of Cubs fan raggin’ on the team. It is an almost poetically profane thing of beauty:

It’s in no way fun so i won’t post it, but it’s easily found on youtube. Alec Baldwin’s godawful rant at his daughter for the horrible crime of not picking up the phone when he called. That will live with me forever. That poor girl.

For completeness it’s worth mentioning Christian Bale flipping out on a crew member who was walking around while he was trying to do a scene and Tom Cruise going on a tirade about people ignoring Covid protocols on set.

My favorite thing about the Bale rant is that people were at first shocked and mad at Bale…and then crewpeople in the industry said “That lighting guy is a prick in real life so good on Bale.”

FWIW I have heard that that clip is actually a fake where it is partially the real Casey but the rant is an impersonator.

What amuses me about this thread is when I saw the post about William Shatner, I laughed because I knew the clip they would bee posting and it ended up bring a different one. He rants so much there is more than one to choose from. The one I was thinking of was where he says to a producer, “You sicken me” because the guy criticized how he says “Sabotage”. Tried to find it but a quick search didn’t turn it up but it was played on Stern all the time.

This may not be exactly what the OP is looking for. But the Tube Bar tapes were secretly recorded, and they are for the ages.

One of many. NSFW.

Tommy Lasorda pulling Doug Rau from the mound in the 1977 World series. Rau made the foolish decision to argue. The organ playing in the background really makes it great.

There are same fake interviews out there, thanks to AI
