While with The Monkees, Tork was involved in the group's most famous musical outtake, "Lady's Baby," a song released in 1995 as a bonus track on the reissue of the group's fifth LP, and inspired by Karen Harvey Hammer, the wife of his business partner Bob Hammer. The Hammers had an infant son, Justin. Peter insisted on getting the cooing of little Justin recorded for use on "Lady's Baby," which required following the baby around the studio with a microphone. Peter's use of baby cooing on a pop album predated by some 30 years the practice later incorporated by country beauties Martina McBride and Sara Evans, who used the cooing of their own children on some of their songs.
