I think there's always been a bit of ambivalence in the Pulp/Blur relationship. They'd obviously known each other for years, going right back to the Paris show in 1991 (which Russell pinpoints as the beginning of Britpop), and stuff like Alex and Damon hopping on their private jet to Iceland in 1996 suggests that relationships were generally cordial. Musically there was a degree of mutual respect bordering on jealousy - Russell told me once that when Pulp first heard Girls and Boys they were kicking themselves for not daring to be quite that cheesy with their own disco tunes. I believe the inclusion of Death Comes to Town, Love Is Blind and I Want You at the Drury Lane concert (with Jarvis pointing out that those songs were from 1987, 1989 and 1984 respecively) was intended to make some sort of point about how Pulp were doing certain things for years before Blur took the blueprint and cleaned up. (Personally I think they're way off the mark on that one, but never mind.) I'm sure Jarvis has also made some low key comments suggesting that Common People and Mile End were written partly in response to Blur's elevation / glamourising of a certain kind of working class lifestyle circa Parklife.
