On the afternoon of 31 December 1984, Allen was involved in a car crash with his then girlfriend, Miriam Barendsen, on the
A57 road in the countryside a few miles west of
Sheffield. A car in front of theirs deliberately slowed for him to catch up, only to speed up as he tried to pass. This went on for several miles until, in frustration, he accelerated to pass, at which point he lost control of the left-hand-drive
Corvette C4, which hit a dry stone wall and entered a field. His left arm was entangled in the seat belt and severed, remaining in the car while he was flung out. Doctors initially re-attached it, but it was later amputated due to an infection. Initially Allen felt "defeated" but, buoyed by "family, friends and hundreds of thousands of letters from all over the planet", he decided to continue playing drums with Def Leppard, and adopted a specially designed electronic drum kit. The band took a hiatus from onstage performances until 5 August 1986 (Allen's first live performance since losing his arm), instead doing a small run of public rehearsal shows in Ireland in advance of their 16 August 1986
Monsters of Rock festival performance at Castle Donington. He has since re-adopted partially acoustic drum kits depending on the setting. ==Equipment==
