How long is this CD? Is it just the music from the fireworks, or are there other things on it? My 2y.o. dd sings Wishes all the time. We got it on video two trips ago and she has watched it over and over. Last trip she sang along while watching and sitting on my shoulders...precious. I would also love to have this CD. We are going back in January, so I can get it then, but was wondering what was on it.
