 After headlining the 2002 Glastonbury Festival , Coldplay returned to the studio and worked on some tracks from the " Songs for # 3 " they had produced earlier . Phil Harvey , the band 's manager , heard " Clocks " and urged them to rework it immediately : " No , you must do that song now ' cause you 're going on [ in the lyrics ] about urgency , and you 're talking about keeping this song back . That doesn 't make sense . "
