That was my story to some extent.
There are two versions of Happy Jack live on youtube. One is of better sound quality but ignores Keith Moon and keeps the camera on anyone but him [intensely annoying, as he drives the song]; the other is of less sound quality but you do see Keith Moon in action. Had to go for the latter:
According to Tony Fletcher’s biography, Moon’s toilet pyrotechnics began in 1965, when he purchased 500 cherry bombs. In time, he would graduate from just cherry bombs to taking out toilets with M-80s. Eventually, he began using sticks of dynamite, his explosive of choice, to destroy toilets.
“All that porcelain flying through the air was quite unforgettable,” Moon recalled. “I never realised dynamite was so powerful. I’d been used to penny bangers before.”
In a very short period of time, he developed a reputation for “leaving holes” in bathroom floors, completely annihilating the toilets, which mesmerised him and enhanced his reputation as rock and roll’s premier hellraiser. Fletcher goes on to state that, “no toilet in a hotel or changing room was safe,” until Moon had detonated his supply of explosives.
Libertarian anthem? It was never done live apparently:
