Old New York cemetery abuzz with a honey of an operation

The silent graves and mausoleums of Brooklyn's Green-Wood cemetery are the final resting place of luminaries who created a buzz when they were alive, like composer Leonard Bernstein, newspaperman Horace Greeley and maverick artist Jean-Michel Basquiat.

It's also home to some 600,000 honeybees and a beekeeping operation that churns out honey sold under the brand name The Sweet Hereafter.

Brooklyn beekeeper Davin Larson, 30, who worked with bees as a youngster growing up in the Midwest, got the idea for the hives while listening to a classical music concert at Green-Wood's central chapel two years ago.
