RHCP confirmed the matter in a facebook post on its official social media page on Saturday.
"We of the RHCP family would like to wish Jack Sherman smooth sailing into the worlds beyond, for he has passed,” RHCP said.
“Jack played on our debut album as well as our first tour of the USA. He was a unique dude and we thank him for all times good, bad and in between. Peace on the boogie platform,” RHCP added.
