YouTube boogie-woogie pianist Brendan Kavanagh is vowing to stand up for free speech despite threats on his life from "little pink" supporters of the Chinese Communist Party. In an incident in London's St Pancras railway station that went viral, Kavanagh rebuffed a request by a group of Chinese flag-wavers to stop filming them while he made a YouTube video of himself playing a public piano. The pianist upped the ante a week later, returning with a plushie Winnie the Pooh toy and a sticker referring to the Tiananmen Square massacre – both of which are banned by Chinese censors. "Popular arts and music, poetry, dancing and singing is a threat to those in power, and I'm really trying to bring back that rock-and-roll rebellious spirit into music," Kavanagh said.
