When Fred Langer's wife, Barbara, was pregnant with Kristin (1980), Fred was inspired early one morning with the phrase "you're the sweetest little fetus". Realizing it was the perfect theme for a humorous song he wrote the lyrics, then set them to an original bluegrass-style tune.

Fred recorded all the parts himself in his home recording studio - guitar, bass, drums, mandolin, vocals - all but the banjo, played by his friend, John Cholewa.

He performed the song on a local noon news program (Carol Nelson) and sold many copies of the 45 RPM record (remember those?) as a result. The record sold for many years in the Florida Hospital gift shop as well and is still used in perinatal classes there.
