The BBC's latest experiment in light, family-friendly entertainment draws to a close tonight with this final episode of John Bishop's Britain, an occasionally funny show in which the Liverpudlian stand-up riffs on a given weekly theme - families, love and marriage, etc - with additional padding from celebrity guests, vox pop interviews with members of the public and short comedy sketches. Tonight's theme is holidays, which gives the charismatic Bishop the chance to air some decent material about his experiences venturing abroad with young children, interspersed with some considerably less amusing chitchat from the likes of Tara Palmer-Tomkinson.
