Tenacre fifth and sixth graders hosted two performances of “Shrek Jr.” yesterday, to the delight of both audiences. The raucous and silly comedy provided many laughs. Sixth graders assisted with choreography, props, and scenery, as well as stage management. All students applied their own makeup (which was extensive) for the show. The annual spring musical is a strong tradition at Tenacre, in which sixth graders take on the lead roles, and fifth graders, the supporting roles.
