Glenn Cornick, the original bassist for Jethro Tull, passed away this weekend in Hawaii, according to reports in Billboard. He was 67 years old. Cornick had reportedly been suffering from congestive heart failure for which he had entered hospice care.

Cornick joined Jethro Tull in one of the band’s earliest incarnations after the dissolution of the John Evan Band; he joined with his bandmate Ian Anderson to form the core of Jethro Tull through its formative years. During Cornick’s tenure with the band, he played on three albums: 1968’s This Was, 1969’s Stand Up, and 1970’s Benefit. Cornick was fired from the band in 1970, after which he formed the band Wild Turkey. He remained with that group until its dissolution in 1973, after which he formed the band Parris with Fleetwood Mac guitarist Bob Welch.

Anderson paid tribute to his former bandmate on Jethro Tull’s website: “Glenn was a man of great bonhomie and ready to befriend anyone – especially fellow musicians. Always cheerful, he brought to the early stage performances of Tull a lively bravado both as a personality and a musician.”

Cornick is survived by his wife, Brigitte Martinez-Cornick; his sons, Alex and Drew; and his daughter, Molly.
