Diamond Bar dropped out of the competition, so the division with Vista's ShowCats, TomCats and Burroughs Men@Work and Powerhouse, was switched to an exhibition. Because of this, the mixed groups were switched around, as you'll see in the results.
Middle School:
1st- Valley Middle School "Showstoppers"
2nd- Black Mountain MS "It's My Forte"
3rd- Calavera Hills MS "Sound Sensations"

I didn't find the line up of choirs, sadly, but I did make an event page for this competition with information I found from a flyer. In addition to the information posted above, the flyer said this festival would run from 12 PM to 9 PM.
It sounds like a really cool venue - hopefully whatever choirs attend have a great time.
