Robert Plant

Much like ITV's Doc Martin, this Welsh valleys-based comedy starring Ruth Jones is a reliable source of gentle laughs, U-rated drama and the odd celeb cameo. Indeed, while Martin Clunes and pals were joined by Sigourney Weaver last year, Robert Plant rocked up in the fictional south Wales town of Pontyberry last week. Things are a little less starry tonight, as the winners of forgotten reality contest Last Choir Standing come to Aunty Brenda's aid. Elsewhere, Stella tries to contact on/off flame Rob, and Michael is forced to compromise.
