Mike puts together a big band for the Glendragon Summer Festival. Everyone has a part to play but as Mike adds players, he doesn't leave any time to rehearse! Meanwhile Fernando forgets the words to his song just before his big performance, Squirt tries being a Court Jester, the villagers gather to watch a knightly play and play tricks on each other for Glendragon Fooling Day. With drums, lute, harp and piccolo, Mike and his friends prove that life is better with a little knight music!
