British rock band Led Zeppelin hosts ‘a freakish Halloween party’ in Chislehurst Caves, London, England in 1974. The party launches the band’s Swan Song Records label and features magicians, fire-eaters and strippers and is attended by various musicians and press. The legendary man-made caves are allegedly haunted and date back to the 9th Century having been used for mining, ammunitions storage, bomb-shelters, a music venue in the 1950s and 1960s and location for British TV and film productions including Doctor Who.
