Sly and the Family Stone’s 1968 record about everybody being different and it making no difference, sung in 1987 by a country superstar and a frog operated by Jim Henson, on the fifth episode of Dolly’s short-lived variety show. Delta Burke, Terence Trent D’Arby and the Oak Ridge Boys were also on that night. Kottke resurfaced it the day Parton died, at 80.
