Many British rock bands from the 70s and 80s saw their band depicted in the 1984 cult mockumentary This is Spın̈al Tap.
Some band members really wince when they see it, reminding them just how pretentious they'd been - whilst others watch it with glee. The truth is, this crazy mock band made up of U.S. comedians is all and none of them - as it's an amalgam of styles and experiences of many rock bands.
One band that seems to have played a part of this mix (largely for it's humor and backstage bickering rather than style) and later celebrated was the English band The Troggs (famous for the song 'Wild Thing').
Although The Troggs never wore black leather, or had a little person dance around standing stones and were never metal, they'll go down as one of the funniest and infamous bands in music history.
The funny thing is, their infamy wasn't earned via a cunning managers' plan to get publicity - the band gained infamy completely by accident.
This infamy began when The Troggs' studio engineer pressed the record button to capture their expletive-ridden tirades whilst they were bickering, floundering around looking for inspiration in the studio (ironically whilst trying to record a track called 'Tranquility') the engineer wanted to share the secret tape with colleagues and friends. However, as the tape became so widely shared by those who heard it, the recording was later bootlegged and became known as 'The Troggs Tapes'.
The rest is history (sprinkled with some f*ckin' fairy dust).
Here, as promised, is a link to the infamous eleven minute expletive-ridden recording (I've also included some extra links below).
The full, 11 minute bootlegged tirade
Years later, a fan did what the original session engineers couldn't do - turn it into a music track (kinda).

Also, if you're wondering where you've heard that weird English accent before, and you're a Star Wars über fan. You probably have. Weirdly, during filming the actors heard Darth speak in this strange, 'West Country' accent (as the actor David Prowse - who played Vader came from there). To all of the actors' relief, except Prowse, James Earl Jones was the one who really gave Vader his voice. No one had told Prowse this seemingly - he only found out once he saw it.
If you've not heard it yet, hear Vader with his West-Country accent during filming Star Wars here:
