During this time, Sloan & Barri continued to do session work with Jan Berry of Jan & Dean, until Jan's near-fatal car wreck in April 1966, which basically ended Jan & Dean's career. They also produced a number of other acts, from Ann-Margret to The Robbs to Canadians Terry Black and Patrician-Anne McKinnon (both of whom had hits in Canada with Sloan-Barri songs) to Dunhill acts such as Shelley Fabares, The Ginger Snaps featuring Dandee Duncan, The Thomas Group (headed by Danny Thomas's son Tony), and The Iguanas (a Mexican band that did not speak English).
