By the early 1960s J & S was in financial trouble, although long-standing contacts with Chess managed to keep it afloat.
A new label, Tuff Records, was created with Chess money, and Abner Spector was told to manage it.
Sanders released music credited to the Hearts, The Jaynetts, The Clickettes, The Poppies, The Z-Debs, The Endeavours, and The Patty Cakes, all made by the same group of girls.
Sanders' (and J & S's) last major production was a psychedelic rock release by Pugsley Munion, the single (JS 0002) and album (SLP-0001) "Just Like You" in 1970.
