Recreations of famous events, slightly embleshied with some great actors/comedians. It's on The in Demand section, some of series 1 and I think all of series 2.
Last night we watched an episode on Live Aid and Bill Grundy vs The Sex Pistols. It was brilliant, especially the Sex Pistols one, the actors playing Johny Rotten and Malcolm M were spot on. If this bit of pop culture history makes you laugh I recommend seeking this out. There's also other episodes, Samuel Becket and his French builder is hilarious.
