Chief Executive Leung Chun-ying has posted a video of himself on Facebook, singing Hong Kong rock band Beyond’s hit songs alongside band member Wong Ka-keung.

Wearing a broad smile, Leung is seen holding a microphone and singing Like You (喜歡你) with Wong, other government officials and members of the Business and Professionals Alliance for Hong Kong (BPA).

The pro-government party was celebrating its third anniversary on Monday night. Besides Leung, other Hong Kong political heavyweights, including Chief Secretary Carrie Lam, Civic Party leader Alan Leong and Democratic Party chairwoman Emily Lau, were also at the event.

Earlier in the night, Leung posted two selfies with Wong, who is a legendary Canto- pop singer and songwriter.

Leung’s video was shared more than it was liked on Facebook. By Tuesday morning, 12 hours after it was posted, the video was liked more than 600 times but shared over 1,100 times.

According to other videos of the same event, the group also sung Beyond’s Glorious Years (光輝歲月), a song about the struggle of South Africa’s Nelson Mandela and the fight for freedom, which attracted some mockery from netizens, the Stand News reported.

Online commenters said Leung may have violated the controversial Copyright (Amendment) Bill by sharing a video of himself singing a copyright-protected song. Critics say the upcoming bill could be used to stifle internet parodies and limit freedom of speech.
