This poem, also known as âTwas the Night Before Christmasâ, tells of the arrival of St. Nicholas on Christmas Eve at the home of the narrator. Brook Forest Voices has filled the classic tale with music and sound effects that will create in the mind of the listener the magic of this special time of year. Clement C. Moore originally claimed authorship, but later the family of Henry Livingston, Jr.âa soldier, landowner, and poet who died in 1828âdisputed Mooreâs claim and argued that the poem was Livingstonâs. Recently, computer aided analysis shows more similarities to Livingstonâs poetry than to Mooreâs..
