Later career and accident
After leaving Gallagher's band, de'Ath joined Ramrod (with Martin) and then he played with the Downliners Sect before moving to the United States. In the mid-1980s, he returned to the UK to produce an album for a band called Road Erect. Around this time, he suffered a serious accident while running to catch a train, which led to the loss of one eye and some brain damage.
Deciding to return to the UK permanently, he eventually made a near-complete recovery, although he was no longer able to play. He had also been told by doctors that his brain damage would kill him within four years, and although this prognosis proved incorrect, he did not want to contact friends only to tell them that he was terminally ill. When Gallagher died in 1995, many obituaries claimed that de'Ath was also dead, and for this reason he stayed away from Gallagher's funeral.
McAvoy had heard that de'Ath had been killed in an accident in 1987. However, he appeared at a memorial service a few months later, having "waited for a suitable moment" to show that he was still alive. McAvoy remembered that de'Ath looked very frail and walked with the aid of a stick.
Little or nothing was known of de'Ath's whereabouts after 1996, until an interview with him was published in Classic Rock magazine in May 2012, within a feature about Rory Gallagher. A few months later in August, de'Ath attended the funeral of former Rory Gallagher and Ramrod band member Lou Martin. De'Ath died on 1 August 2014, aged 64, after a long illness.
