So, while stumbling around the BBC iplayer for something a little bit "spacey" to watch while on a bit of a cruise I stumbled on this:
The Entire Universe (in one hour)
Eric Idle persuades Professor Brian Cox to present a lecture on the birth of the entire universe. Brian soon realises Eric is actually hosting a comedy and musical extravaganza.
You have Warwick Davis, Noel Fielding, Hannah Waddingham and Robin Ince alongside Eric and Brian to provide a spoof, yet educational, musical.
