Bob Weston, former Fleetwood Mac guitarist on the albums Penguin and Mystery to Me, died Tuesday from a gastric intestinal hemorrhage at the age of 64, according to reports.

Weston's official Web site said police found him dead in his home in north London on Tuesday after friends became concerned that they had not heard from him for several days. Perezhilton.com says the suspicion was raised when Weston never showed up to work on a new album with Rolling Stones guitarist Mick Taylor. According to Reuters, London police confirmed Weston's death, and said they were not treating it as suspicious.

Weston replaced guitarist Danny Kirwan joined for Fleetwood Mac in 1972, going on tour with the band for two years. It was during the American tour with Mick Fleetwood that Fleetwood discovered Weston having an affair with his wife, Jenny Boyd. Weston was subsequently fired in 1974.

After his short time with Fleetwood Mac, Weston went on to release several solo albums and played with musicians such as Long John Baldry, Murray Head, Sandy Denny and Steve Marriott, and bands such as Ian Wallace's All-Stars Band, according to Billboard.com.

My family and I have lost a dear friend; the world has lost an enormously talented musician, with unfinished business, said Weston's Web site webmaster and friend Steve Fairhead on the Web site.

Weston is survived by his younger brother Peter.
