Mongrel, the supergroup formed by Babyshambles' Drew McConnell, Reverend And The Makers' Jon McClure and former Arctic Monkey Andy Nicholson are set to play a gig on a carnival float tomorrow (June 21).
The group will perform without Nicholson at Love Music Hate Racism's carnival parade through central London.
McConnell and McClure, joined by British-Iraqi rapper LowKey, are set to play on the back of a mobile float complete with sound system.
The parade will begin at the GLA offices on Tooley Street and will end in Trafalgar Square.
The event follows a stunt by the campaign during which they targeted Greater London Assembly member Richard Barnbrook, who represents the British National Party.
The "mock eviction" yesterday (June 19) saw activitists and several musicians mount a protest at London's City Hall.
"It's quite easy to get caught up in words and to try and over-articulate something very simple," explained Get Cape. Wear Cape. Fly's Sam Duckworth. "I don�t want a facist organisation beeing involved in the running of London, or any borough for that matter. Notice is being served; it's time to get the BNP out of the GLA and out of politics altogether."
