FOREST LAWN was on Tom Paxton's LP "Tom Paxton 6" which came out in 1970.

"The American Way of Death" by Jessica Mitford, was published in 1963, and an updated revision "The American Way of Death Revisited" in 1998.

Forest Lawn, the cemetery, was also an inspiration to Evelyn Waugh, whose satirical novel "The Loved One: An Anglo-American Tragedy" was published in 1948.

Paxton was familiar with both works, and cited them both in the notes to "The Compleat Tom Paxton [Even Compleater]" (Rhino Handmade, 2004) – according to this footnote at Wikipedia.
