Paul Michael "Oz" Bach (June 24, 1939 – September 21, 1998) was an American folk musician and guitarist for the 1960s group Spanky and Our Gang. Bach entered music in 1962 as a guitarist, singer and comedian, before switching to bass in 1963. He then played as a back-up musician for Fred Neil, Tom Paxton, Bob Gibson and Josh White. In 1965, Bach and his friend Nigel Pickering made the acquaintance of Elaine "Spanky" McFarlane, a singer from Chicago. The three later became Spanky and Our Gang. The trio released their eponymous debut album in 1967.
