You remember Sly Stone, right?

Via TMZ:

Sly Stone — ex-frontman of the ’70s funk band Sly & the Family Stone — is admitting he still abuses cocaine and alcohol … but the 68-year-old singer insists he WANTS to clean himself up.

Stone — who’s currently living in a van in L.A. — spoke candidly about his substance abuse issues yesterday, insisting he hasn’t used drugs or taken a sip of alcohol in “a week and a half.”

A discombobulated Stone claims he’s chosen a rehab center — and insists he’s serious about it … saying, “I will be there.”
