There's a post credit scene that shows the police patting down Moira Stewart, earlier referenced by the BAFTA official as a likely dealer of Ronnie Corbetts cocaine; she then signs to Andy that he's a dead man.
Chris Martin, of whom the episode was named after, performs two songs. One is his own 'Fix You' which he performs within the sitcom 'When The Whistle Blows', and the other during the end credit sequence. The credit sequence uses the same 'Tea for the Tillerman' song by Cat Stevens but it's performed by Chris Martin here.
Chris Martin co-wrote a song on Ricky Gervais' album "David Brent: Life on the Road" called "Electricity". The album accompanied The Office spin off film of the same name as the album that also starred Ricky Gervais.
