This song has been heard many times since Sept. 11, 2001.  Here, I have arranged it in imitation of something mentioned on the main page of the site you are on: children's records of 1950s vintage.  The 2 versions available here are each 1:42 long and may be a little more up-tempo than what you are familiar with; the only difference between them is in the harmonized clarinet part in the 5th measure from the end (1:35 into the selection). You may also notice the underlying chords are somewhat different from what you already know. But even those children's records used the idea of adding embellishments when the original theme was played the second time.
