I just that TC, upon seeing Sly & The Family Stone in '67, likened them to "James Brown and Frank Zappa under the same roof."
Peter (who, realizing that there actually those among us who might not get the reference, will add that "TC" is Tom Constantin, Grateful Dead keyboardist about '67-'69 - and will furthur add: 2 drummers, 2 guitarists, 2 keyboardists; why didn't they just go all-out and add another bassist?)
