"One's on the Way" (1971)
This sardonic Shel Silverstein gem from 1971 follows a pregnant, frazzled Kansas housewife bemused by the glamorous exploits of such Seventies icons as Elizabeth Taylor and Jackie Onassis. Lynn takes dripping faucets and demanding kids in stride, yet by song's end hopes "it ain't twins again." In 1966, when the first of Lynn's more than 20 grandchildren was born, the last of her six children, Peggy and Patsy, were babies. A Number One hit and a Lynn concert mainstay (with updated cultural references including First Lady Michelle Obama), this understandably wasn't her twins' favorite.
