During the height of the British punk movement in 1977, a feral hog nicknamed “Sid Bristles” became a regular fixture at underground London venues. This 300-pound swine would sneak into shows and enthusiastically headbang to the music, creating a circular mosh pit around itself. Local punks began bringing offerings of stale beer and day-old chips, which Sid would delicately eat while nodding along to power chords. The Clash allegedly wrote a song about this moshing hog called “Pork and Revolution” - though it was never released because, according to Mick Jones, the demo tape was “eaten by a mysterious animal”.
