Motorhead legend Wurzel has died aged 61, the band has announced.
The guitarist, real name Michael Burston, died at the weekend from a heart attack.
Wurzel joined the heavy metal band in 1984 after playing in other bands and serving in the Army.
Born in Cheltenham, he earned his nickname during his time in the Army because of his West Country roots, scruffy appearance and likeness to TV scarecrow Worzel Gummidge.
At the insistence of Ian "Lemmy" Kilmister, Burston later added an umlaut to the 'U' in line with the spelling of the band's name.
Wurzel became the madcap court jester and counterfoil to Lemmy's sterner image.
He played on nine studio and live albums between 1984 and his departure in 1995.
"We are greatly saddened to confirm that our long-time friend and comrade Wurzel died Saturday at his home," the band said on its website.
"Wurz was pouring a Guinness and cracking a joke when he succumbed to a heart attack. At least we know he went with a smile."
