“I may have taken the term ‘40th anniversary celebration’ a little too seriously,” chuckles Public Image Ltd. leader John Lydon.: In the name of their ruby red year, PiL arrives at its local anniversary tour stop promoting both a career-spanning box set and documentary, The Public Image Is Rotten. No one’s more surprised to be fronting the UK dub punks 40 years later than the former Johnny Rotten, enfant terrible of the Sex Pistols.: “It proves the endeavor is something I truly believe in,” replies the singer, 62, in his characteristically wry Cockney tone. “I’m consistent with things I know are right, and will continue to be so. We stick by each other, which is phenomenal for a band after this length of time.”: Lydon proudly notes former Pop Group drummer Bruce Smith, former Damned/Mekons guitarist Lu Edmonds, and bassist Scott Firth as PiL’s longest-running lineup, which clocks in at nine years.: “They’re not all originals, but I am! And that’s all that matters,” he chuckles.: The frontman remains the last original bandmember standing, but that first lineup of Keith Levene (g), Jah Wobble (b), and Jim Walker (d) set an evolutionary tone with initial 1978 single “Public Image,” which took the Pistols’ raw rock sound, refined it, then destroyed it. Lydon claims this didn’t happen by design.: “It’s an odd way to approach pop music, because we didn’t know any better. And we didn’t need to! I always say PiL’s essence is pop music. You don’t need to overelaborate. Keep [the music] succinct and to the point. Let the audience unravel it deeper, which they will or they won’t, according to their whims.: “But keep everything almost underplayed, rather than over-, and you create far more information.”
