Thousands of people took to the streets around the Rockefeller Center in New York on Wednesday night to watch its annual tree-lighting ceremony.

Onlookers were serenaded by Rod Stewart, Cee Lo Green and The Muppets before the lights were switched on illuminating the tree's more than 30,000 lights.
