Jethro Tull were formed “out of the ashes” of The John Evan Band and McGregor’s Engine, the blues band Abrahams formed with Clive Bunker in the Luton/Dunstable area, said Anderson.
Abrahams, external played on Tull’s first album, This Was, but left shortly after it was finished, and went on to found another successful band, Blodwyn Pig.
After pursuing a solo career between 1971 and 2017, he retired from performing following a stroke.
Anderson described him as a “homebody” who “liked to gig around the home counties”.
He said: “We all offer our condolences to Mick’s family and close friends, who can feel justifiably proud of his achievements and musical legacy.”
