The five of a kind are stations on the Jubilee tube line in London, derived from: 26/27 (London Bridge), 40/41 (Stanmore), 46/47 (Waterloo), 3/34 (Baker Street) and 10/39 (Westminster). LOVELY JUBBLY (32/12D) suggests mispronounced praise. ORATE/ERATO were both accepted at 46A, as were SETTER/TESTER at 34D. Title: the line’s colour on tube maps.
