Blue Mountains flash mob singers wake up commuters at Central Station | VIDEO

Sing for the Climate represented the Blue Mountains at the Extinction Rebellion protests in a flash mob at Sydney's Central Station on Monday, October 7.

Much to the curiosity and delight of the "audience", nearly 100 singers gave a rousing rendition of what is becoming the movement's anthem, We Need To Wake Up, in four-part harmony and complete with arm gestures.
