Information for Tinsel at The Theatre By The Lake, Keswick (Kids show). Tinsel is the tale of one little boy who dreams of being the fairy on top of the Christmas tree! He can sing, dance, and wear a sparkly tiara as well as anyone else - but to get to the top, he'll have to convince a whole tree of doubting baubles and naysaying ornaments that anyone can shine if they're given the chance!
