Kicking off three-and-a-half hours of Ronnie action, Ronnie Corbett and Ronnie Barker star in a festive edition of their comedy show from 1984, the first in an evening of programmes dedicated to the Two Ronnies. West End star Elaine Paige joins in the sketches, jokes and songs, featuring the Ballad of Snivelling and Grudge and A Film Story with Peter Wyngarde as Sir Guy. Patrick Troughton and John Owens also appear. At 9.00pm there's a repeat of Being Ronnie Corbett (a fine documentary charting the comedian's long career, including interviews with Miranda Hart, Rob Brydon, Stephen Merchant, Bill Bailey, Matt Lucas, David Walliams, Catherine Tate, Reece Shearsmith - no, hang on, there's more - Bruce Forsyth, Michael Palin, Ben Miller, Jessica Hynes, Jon Culshaw, Kevin Bishop, Tamsin Greig and Stephen K Amos), then there's The Two Ronnies: The Studio Recordings, followed by Ronnie Barker: A BAFTA Tribute at 10.30pm, in which you can expect contributions from David Jason, Peter Kay, Gene Wilder, Ben Elton, John Cleese, June Whitfield, Rob Brydon, Peter Hall, Eric Sykes, Tom Stoppard...
