Scissor Sisters's "The Other Side" from the album Ta-Dah is partially based on "In the Machine", the first third of Specimen Days. Michael Cunningham is a favorite writer of one of Scissor Sisters' lead singers, Jake Shears, and gave Shears an advance copy of Specimen Days. Shears wrote "The Other Side" right after reading it.[2]
Hanya Yanagihara has said she considers her novel To Paradise to be "in conversation" with Specimen Days.[3]
