Not as psycho as the end of this Top of The Pops appearance in 73.
Pete really loses it at the end. I think this was around the time Roger punched him in the studio.

The amazing thing is how Keith Moon didn’t lose it.
The drumming continues on well after his kit is completely destroyed.
That’s a rock legend! :)
