This week, the Professor of Ignorance John Lloyd and his new curator Noel Fielding welcome the Newsjack presenter and half of the double act Gentlemen of Leisure, the writer and comedian Nish Kumar; Professor of Experimental Architecture and TED fellow Rachel Armstrong; and the award winning composer of choral music, stage musicals, film and TV scores, Howard Goodall. This week, the Museum’s Guest Committee speculate on the appeal of a 50 year-old piece of vinyl; a magic spell in a bottle; and an extinct piano with no keys. The show was researched by Mike Turner and Anne Miller of QI. The producers were Richard Turner and James Harkin. It was a BBC Studios Production.
