 Songs and spoken-word productions about the dangers of drug abuse joined the parade of pathos on radio airwaves, ranging from three-minute morality plays to lamentations (from the parental perspective) on the generation gap.These include "Once You Understand" by Think (U.S. #23, 1971) and radio and TV host Art Linkletter's Grammy-winning single "We Love You, Call Collect" (U.S. #42, 1969).Recorded before his daughter Diane's apparent suicide in 1969, the record also included Diane speaking the reply, "Dear Mom and Dad".
