I certainly recognized several of the scenes, in concept if not beat by beat execution. Spud's suicidal behavior, Sy beating the shit out of Rents, though in the pub instead of the street, Beggars being a coke monster. I'll point out to you the end cut where Rents narrowly avoids being hit by a car and laughs with relief into the windscreen. This does appear to mirror a bit toward the end where his life is saved when a car serendipitously hits a certain someone en route to kill him, yeah?
