Alan Arkin, the actor, was born in 1936, I believe, making him just four years older than me. The next information, from "Wikipedia," may shed light on the subject. David was Alan's father.

For the actor of the same name, see David Arkin.
David I. Arkin (died October 8, 1980[1]) was a teacher, painter, writer, and lyricist, and is the father of actor Alan Arkin.

Arkin was born in the United States[2]. In 1945, Arkin moved his family to Los Angeles, California to take a teaching job. Arkin attempted to obtain work in the entertainment industry, but was unsuccessful. An eight-month Hollywood strike cost Arkin a set designer job, but the greater blow was as a result of the McCarthy "witch hunt". Arkin, a leftist, was accused of being a communist but Arkin refused to answer questions regarding his political affiliation. As a result, he was fired from his teaching job and was unable to gain work in Hollywood. Arkin challenged his dismissal, but did not achieve exoneration until after his death. He died of cancer in October, 1980, at the age of 73 at his home in Silverlake, California.[3]

Arkin's most memorable song-writing contribution was in creating the lyrics to the song "Black and White," with music by Earl Robinson in 1954.[4] The song was written to celebrate the United States Supreme Court decision of Brown v. Board of Education striking down racial segregation in public schools.

Note that "The Klan" is not mentioned in this piece.
