I know that Sly Stone is/was a multi-instrumentalist, and that he was responsible for most of the instrumentation on There's a Riot Going On, but I still don't know exactly how many instruments he played or how proficient he was at them which I would be interested in knowing.

I know that he play bass on You can make it if you try,
If you want me to stay& that he play most stuff on
"There's a riot going on".I wish there was some footage of him
recording in the studio.That would B just mindblowing.
Bootsy Collins said once that Sly was the most talented dude
he ever met.
