Nursery Rhymes - Happy and You Know It

"If You're Happy and You Know It" is a popular repetitive children's song, of uncertain authorship. The song is supposed to belong to the public domain, although many of the different versions of the song are still protected by copyright law. One such version was written by songwriter Alfred B. Smith (1916-2001). It has, like many familiar childhood cantations, been altered in various ways over the years for various uses.
