We of the RHCP family would like to wish Jack Sherman smooth sailing into the worlds beyond, for he has passed. Jack played on our debut album as well as our first tour of the USA. pic.twitter.com/2vpZ3wrYRN
Sherman was believed to have died on August 18, but the news wasn't made public until last night, The Sun reported.
Sherman replaced Hillel Slovak on the 1983 debut album and the subsequent Freaky Styley, but was replaced by Slovak before the latter album was released.
