Peter's friend, Karen Harvey Hammer, had a son named Justin who became the inspiration for Peter's song "Lady's Baby."
Here's a page of Andrew Sandoval's liner notes from The Birds, The Bees & The Monkees deluxe edition box set detailing the complicated recording history of the track:
Davy Jones spoke of his fondness for "Lady's Baby" in 1994 when The Birds, The Bees & The Monkees was released on compact disc by Rhino Records:
"They laugh and joke about that ["Lady's Baby"] – it cost as much to do as 'Good Vibrations,' that record. But that was a true-to-life thing. He was living with a woman at the time, and she had a little baby, and that changed his life, you know? That gave him something to think about. He was being downtrodden by the studio in regards to his recording, his playing, his songs and everything else. But Peter Tork was the salt of the earth. It wasn't just Hari Krishna, waterbeds, and brown rice – that guy was a very accomplished musician. It's a nice song, it's true, it's got the warmth and everything of what he was living. I remember it so well – it's a real tune. I love it."
Peter performed "Lady's Baby" during his 'In This Generation' solo tour in 2013:
