This week Fionn, Hugh and Laurence hop on board a carousel of nostalgia. First up, Mad Men: with just a few episodes left to come, the hit AMC show has entered the 70s, and with it its character's clothes. There's a lot more to these costumes than meets the eye, as Tom Fitzgerald, who has analysed every show's fashion on his blog tomandlorenzo.com, explains. But can the costumes reveal Don's ultimate fate?

In part 2 it's time to look at vintage Irish culture, and helping with that is Brian McMahon, whose Brand New Retro blog catalogues the styles, magazines, advertisements and agony aunt columns of Ireland in days gone by.

Plus, Hugh is questioning the fiscal responsibility of George Bailey in It's a Wonderful Life, Laurence is surprised by Ghostpoet's full band, and Fionn flags the end of FX show Justified.
