From the wiki: “‘Black and White’ was written in 1954 by David I. Arkin (father of actor Alan Arkin) and Earl Robinson, inspired by the United States Supreme Court decision that year of Brown v. Board of Education that outlawed racial segregation in US public schools.
“‘Black and White’ was first recorded by Pete Seeger in 1956 and released on his album Love Songs for Friends and Foes, followed by Sammy Davis Jr. in 1957 (for a limited-edition Anti-Defamation League EP) and also a version recorded that year, too, by co-writer Robinson. The original folk song lyrics (not used in either Greyhound’s or Three Dog Night’s versions) include the line ‘Their robes were black, their heads were white’, referring to the US Supreme Court justices involved in the 1954 decision.
