To mark the 50th anniversary of Amnesty International, the organization is bringing its famed UK fundraiser, The Secret Policeman's Ball, to the US for the first time on March 4 at New York City's Radio City Music Hall.

The benefit concert will feature Coldplay, Mumford and Sons, Russell Brand, Reggie Watts, and political comedians Jon Stewart and Stephen Colbert from the Comedy Central Network. Also on the bill are Noel Fiedling, Sarah Silverman, Jack Whitehall, and Kristin Wiig, among others.

While most tickets have been sold for Radio City Music Hall's 6,000 seat venue, there are a few seats remaining via Ticketmaster as of February 29.

For US residents, the concert will stream live via streaming site Epix. The event will also be broadcast on British television shortly after the live gig.
