Police say Weston’s body was found in his north London home on Tuesday after neighbors raised the alarm.

Police said Friday that his death was not being treated as suspicious. An autopsy revealed the causes of death as gastric intestinal hemorrhage, cirrhosis of the liver and throat problems.

Weston joined Fleetwood Mac in 1972 as replacement for Danny Kirwan, and played on the band’s albums Penguin and Mystery to Me.

But during an American tour the next year, Mick Fleetwood discovered Weston was having an affair with his wife, Jenny Boyd. Weston was fired.

He released several solo albums and played with musicians including Long John Baldry, Murray Head, Sandy Denny and Steve Marriott.

He is survived by a brother.
