In addition, there have been instances of the interactions of participants being engineered by the programme's producers. For instance, Paul and Nick were flown back to England at Granada's expense for the filming of "35 Up" and "42 Up" respectively. In addition, Paul was flown back again for "49 Up" and visited Symon; Symon and his wife were in turn flown to Australia to visit Paul in "63 Up". As well, Bruce was affected by Neil's plight and offered him temporary shelter in his home shortly before "42 Up", allowing Neil time to get settled in London; despite Neil's eccentricities during his two-month stay, they clearly remained friends, with Neil later giving a reading at Bruce's wedding. In "56 Up", Suzy and Nick are interviewed together, having become friends due to their shared rural upbringing.
