An excellent party chez Jeremy and Jill Lever following the first day of the 20th Century Society's 1970s conference. I notice Mary Stirling, Jeremy Dixon and Julia Somerville, Robert Maxwell and Celia Scott, Andreas Papadakis and Sheila de Vallee, and Bevis Hillier among the guests at the house off Ladbroke Grove. Spectacular upper floor views include an uninterrupted vista towards Erno Goldfinger's Trellick Tower. Naturally I find James Dunnett deep in contemplation of this object. The rest of us spend most of our time trying to think about something good which happened in the 1970s which wasn't an exuberant expression of a 1960s idea . . .
