1. Using Ultravox, a nod to the period but a nod too to Ashes to Ashes (it’s the song used when Alex first wakes up in 1981). It’s not the first time Who and Life on Mars/Ashes to Ashes using the same song either. Britney’s Spears Toxic, heard on the End of the World episode as a song of old Earth was also the song they used on Sam as a form audio stimuli (where he briefly saw the Manchester of 2006. 

2. Liam Cunningham, aka Davos Seaworth on Game of Thrones as a Soviet Submarine Captain. Yep that works too. At least he isn’t trying the Scottish-Russian-Connery accent.
