"Teach Your Children" is a song written by Graham Nash in 1968 when he was a member of the Hollies. Although it was never recorded by that group in a studio, the Hollies did record it live in 1983. After the song was initially recorded for the album Crosby, Stills & Nash in 1969, a much more enhanced version of the song was recorded for the album Déjà Vu by Crosby, Stills, Nash & Young, released in 1970. As a single, the song peaked at No. 16 on the Billboard Hot 100 charts that year. On the Easy Listening chart, it peaked at No. 28. In Canada, "Teach Your Children" reached No. 8. Reviewing the song, Cash Box commented on the "incredible soft harmony luster" and "delicately composed material." Billboard called it "a smooth country-flavored ballad that should prove an even bigger hit on the charts [than 'Woodstock']." Stephen Stills gave the song its "country swing", replacing the "Henry VIII" style of Nash's original demo.
