In the first of three, hour-long specials from Edinburgh, The Culture Show features the best in theatre, art, dance, books, comedy and cabaret from week one of Europe's biggest cultural festival. Presenter Sue Perkins - herself an Edinburgh veteran - invites today's comic stars to recall their debut on the Edinburgh Fringe, which sees The Assembly Rooms and The Gilded Balloon celebrate their 30th and 25th years respectively in 2010. Previewing the Festival which launches tomorrow night (13 August), The show goes behind the scenes with the National Theatre of Scotland as they rehearse their latest production, Caledonia. The Culture Show also previews the International Festival's opening night concern, El nino, with the BBC Scottish Symphony Orchestra performing John Adams's musical interpretation of the nativity story.
