Bom! went the bear

BOM! went the bear on the big bass drum. Ting-ting-a-ting-ting-a Strum strum strum. Bear loves to play his big bass drum. On his own. Making as much noise as he can, marching around like he's king of all the land. It looks like so much fun that soon he's joined by all manner of enthusiastic musicians. But with so many animals determined to deliver a command performance, is there room for Bear to march to the beat of his own drum?
