"'The Troggs Tapes' is an infamous compilation of studio chat said to have inspired the Spinal Tap rockumentary. These recordings, available on bootleg, were made during a session and display, according to The Penguin Encyclopaedia of Popular Music, 'instrumental incompetence, mutual recrimination and much foul language'. They inspired the sequence in which Tufnel and St Hubbins have their row in the Rainbow Trout Recording Studio."

Available in both Real and MP3 formats. Short, historic, and fairly hilarious.
