of Crisp in 1997, Sia moved to London to follow her relationship with boyfriend Dan Pontifex. Several weeks later, while on a stopover in Thailand, she received the news that Pontifex had died after being in a car accident in London. She returned to Australia, but received a call from one of Pontifex's former housemates, who invited her to stay in London. Her 2001 album Healing Is Difficult lyrically deals with Pontifex's death: "I was pretty fucked up after Dan died. I couldn't really feel anything." Sia recalled the effect of his death in a 2007 interview for The Sunday Times: "We were all devastated, so we got shit-faced on drugs and Special Brew.
