Comedian and space nerd Dara O Briain joins Rattus as guest host for a special show that marks the anniversary of the 1969 moon landings.

Rattus has launched his own radio station (‘BBC Radio Number Two’) and who better to advise him on the songs he should be playing than social media star Holly H? Together, they bring us a collection of some of the best songs of this series, plus new material from some of the famous historical faces we meet along the way.

Doctors Chris and Xand van Tulleken join Rattus for a selection of old and new sketches relating to bodies.
