We put Marc in a one week day camp with Stagecoach, a drama arts school (www.stagecoachschools.ca). The staff there did an awesome job of bringing out the best in all the kids, especially with Marc. I'm very grateful for the care and consideration they gave to Marc.
Here's a rough cut of the Friday afternoon show they did. It has the parts that Marc was in (thank goodness YouTube now allows 15 minutes per video -- saved me some editing).
