The performances of "Under the Westway" and "The Puritan" on 2 July were the first live performances of new material by the whole band since 30 January 1999, when all four members played a fan-club only concert at Finchley Arts Depot, London. This was at the start of the 13 tour, in which all songs from that album bar two were premiered.
Matthew Horton of the NME wrote that the song was "initially jarring, with beats pulled straight out of a cracker, it soon unveils a "happy sad" – just one of many meta-lyrics – melody and the kind of ludicrous clowning bounce that Blur have always managed alongside the more world-weary stuff." Horton also stated that the song "pulls together the greatest titbits from the Blur catalogue, and finds room for traces of Gorillaz and all the other malarkey Damon Albarn's turned his magpie mind to. So it's bumped along by the kind of plastic electronic parp you could snap up on Freecycle, echoing Gorillaz' "Doncamatic" in its cheap-as-chips bop, and wigging out to a 'chorus' of frenzied fuzz-bass that'd slot nicely into the more annoying nooks of Think Tank."
