In 1967, Entwistle married his childhood sweetheart Alison Wise and bought a large semi-detached home in Acton, filling it with all sorts of extraordinary artefacts, ranging from suits of armour to a tarantula spider. His eccentricity and taste for the bizarre was to remain with him throughout his life. When he moved to Stow-on-the-Wold in 1978, his 17-bedroom mansion, Quarwood, resembled a museum. It also housed one of the largest guitar collections belonging to any rock musician.
He was known to walk across the Fosseway and along the footpath, through Maugersbury and up to the Bell for a drink. Until a few years ago the Bell had a bar dedicated to John with memorabilia and a juke box playing only Who classics.
Sadly, John died in Las Vegas on 27th June 2002. His funeral was held at St Edward's Church on 10th July 2002 with speakers erected outside of the church to cope with the crowds. He was cremated and his ashes were buried privately. Quarwood and some of his personal effects were later sold off to meet the demands of the Inland Revenue; coincidentally, he had worked for the agency from 1962-1963 as a tax officer before being demoted to filing clerk, prior to joining the Who.
