A group of people gathered in downtown Regina during the noon hour Thursday to rally in support of freedom of expression and perform a song called Harperman.

The song was written by Tony Turner, a physical scientist at Environment Canada and longtime singer-songwriter in Ottawa's folk music scene. Turner was sent home in mid-August, according to his union, over concerns that his song breached Environment Canada's value and ethics code.

The song touches on the Duffy trial, among other issues, and includes highly political lyrics like "Who muzzles the poor scientist?" Its chorus ends with the blunt line "Harperman, it's time for you to go."

The original video on Youtube has been viewed more than 600,000 times since its release in June.

The song was performed in Regina as part of a Canada-wide sing-along.

"Writing a protest song about government and performing it is not a reason for job action," Bernadette Wagner, a Regina woman who helped organize the rally, said in a news release about the event. "The right to freedom of expression is guaranteed in Section 2 of the Canadian Charter of Rights and Freedoms."
