Greatest Hits is a greatest hits album by American recording group Sly and the Family Stone, released on November 21, 1970, by Epic Records. Comprising five singles and their b-sides along with one additional single and one album track, it includes all of the singles from the albums Dance to the Music (1968), Life (1968), and Stand! (1969), and all of their charting B-sides. Three tracks released as singles in 1969 appear on album for the first time here: "Hot Fun in the Summertime", "Everybody Is a Star", and "Thank You (Falettinme Be Mice Elf Agin)". The versions on this compilation are not the single mixes in all cases; some songs appear here in their album lengths and mixes.
