"Goodnight, Ladies" is a folk song attributed to Edwin Pearce Christy, originally intended to be sung during a minstrel show.
Merrily we roll along, o'er the dark blue sea.
Note: the "Merrily We Roll Along" chorus has the same melody as "Mary Had A Little Lamb".
Charles Ives quoted the song in A Symphony: New England Holidays (1897–1913): I. Washington's Birthday, towards the end of the movement.
Meredith Willson features the piece as the tenth number in The Music Man (1957).
