The band was rumoured to be reuniting for the gig, but Lydon accuses Geldof of fabricating the rumours to boost interest in the event, without ever consulting him about playing.
He says, "The way Bob Geldof used the Sex Pistols to pontificate his Live 8 message! He did not speak to us. He implicated us as being part of that Live 8 thing and we weren't even asked.
"So he's using our name to sell his message, but he didn't have the decency to phone me and ask.
"So he's a c**t."
