Before Julie Andrews first sang "A Spoonful of Sugar," its songwriter found inspiration for the iconic Mary Poppins tune in an unlikely place.
The late Robert B. Sherman wrote it with his brother, Richard; many of the duo's songs are featured in classic Walt Disney films. At StoryCorps last month, Robert's son, Jeffrey, said that it was telling his father about getting the polio vaccine as a child that sparked the lyrics for the famous song.
Jeffrey, now 63, said his dad had a way with words.
