Backstreet Boy Brian Littrell joined the fun by playing an apple shaker and wood block, Nick Carter tapped a tambourine, Kevin Richardson took on the güiro, A. J. McLean picked up a maraca and Howie Dorough clapped a pair of coconuts.
Fallon, meanwhile, kept busy with a bass drum, a Casio keyboard and an apple shaker.
