Even The Libertines are nowhere near headline status nowadays, and until they reformed they held something of a semi-mythical status.
It's interesting how the American acts of that era - The Strokes, The Killers, even KOL who are still very much a festival/arena headline sized act - have fared so much better than their British counterparts. Only ones I can think of that still hold up well commercially today are Arctic Monkeys, who were always a huge name, and Kasabian (up until the Tom Meighan controversy) who had more of a crossover appeal and were less guitar oriented than the others.
It's just crazy looking back how once upon a time Razorlight and Franz Ferdinand were deemed to be on the same level as the likes of RHCP, Muse and Pearl Jam by the R&L promoters.
