Tabloid favourites Pete Doherty and Carl Barat produced a typically chaotic performance as the Libertines returned to England for the first time since their reunion.
The Libertines, playing at the latest Barclaycard British Summer Time gig in London's Hyde Park, were interrupted part-way through second song Boys in the Band as the 60,000-strong crowd were asked to spread out, due to the surge as the indie rockers opened.
Doherty made an impromptu appearance on drums during the first ten-minute interlude, playing percussion on a rendition of the White Stripes' Seven Nation Army and then strumming his guitar to the Foundations' Build Me Up Buttercup as audience members were urged to behave, and desist from throwing fireworks and flares during the set's first few minutes.
The greying Doherty also used one of very few interactions with the audience to pay tribute to football club Queens Park Rangers, Smiths guitarist Johnny Marr and Gerry Conlon - who was among four people wrongly imprisoned for the 1974 IRA Guildford pub bombings, and who died last month - during a hit-filled set, the band's first in more than four years in the capital.
Barat and Doherty - previously romantically linked with model Kate Moss - put their once much talked about personal differences aside as they frequently shared a microphone and embraced mid-set as the sun went down on Hyde Park.
The set included crowd favourites such as Can't Stand Me Now, Don't Look Back Into The Sun and What A Waster before more interruptions - mid-song - as Barat was instructed to request that bare-chested fans stop scaling the delay tower.
A singalong of pre-school staple the Hokey Cokey closed the show.
The band also used the gig to announce two further London concerts, at the Alexandra Palace, on September 27 and 28.
