Ex-Fleetwood Mac guitarist Bob Weston dies at 64

(CBS) Bob Weston, the British guitarist who played with Fleetwood Mac in the '70s, has died. He was 64.

Police found Weston's body in his London home on Jan. 3 after friends became concerned about the "the lack of response, having not seen him for a couple of days," explains a message on BobWeston.com.

"He was found in his bed with the TV on; it is presumed he was asleep and didn't suffer," according to a post on the website.

An autopsy revealed the causes of death as gastric intestinal hemorrhage, cirrhosis of the liver and throat problems, reports the Associated Press.

"He was in fine spirits, and was involved in several new projects," his website reveals. "He also seemed to be very fit."

Weston joined Fleetwood Mac in 1972 as a replacement for Danny Kirwan. He played on the albums "Penguin" and "Mystery to Me."

While on tour in late 1973, drummer Mick Fleetwood found out that Weston was having an affair with his wife, Jenny Boyd, according to the AP. Weston was fired, and the rest of the tour was scrapped. Two years later, Mac staples Stevie Nicks and Lindsey Buckingham joined the group.

Weston, a Liverpool, England native, released solo material through the years and recorded with various music artists, including Long John Baldry, Murray Head, Bob Welch and Steve Marriott.
