Despite the success of the 'Rock Against Racism' concerts (an ANL affiliated campaign), some of the punk rock bands that had been outspoken opponents of the NF from the start—such as the Sex Pistols/PiL —refused outright to have anything to do with an organisation they perceived as little more than an SWP front. (The Clash did headline the 1978 Carnival however). Tony Cliff told a "Guardian" reporter during the March 1979 crisis, "The leadership of the ANL is the SWP and we don't give a damn".
