His longtime companion, Young Kim, confirmed his death to The New York Times.
The 1970s band was fronted by Johnny Rotten (real name: John Lydon), with Steve Jones on guitar, Paul Cook on drums and Sid Vicious as the bassist. The group's songs included "Anarchy in the U.K." and "God Save the Queen." Their one album, released in 1977, was titled Never Mind the Bollocks: Here's the Sex Pistols.
McLaren also briefly managed the New York Dolls and Adam and the Ants, and he created Bow Wow Wow.
He was a denizen of the art and fashion worlds. In the '70s, he teamed with then-business partner and girlfriend, fashion designer Vivienne Westwood, on a clothing shop they at one point called SEX.
He also had a solo music career, putting out albums that were an eclectic blend of genres — Duck Rock in 1983, mixing hip-hop and elements of world music, and Waltz Darling in 1989, introducing voguing.
McLaren is survived by Joe Corre — his son with Westwood and founder of the lingerie firm Agent Provocateur — and Kim.
