I'm exhausted now... Try this one: Precisely, which very famous address houses the UK's oldest grand piano?...
Well done Beth. Apsley House known as No.1 London due to it being the first house beyond the Western Gate of London at Knight's Bridge. The piano was made in 1772 and is the oldest known piano to feature 'loud and soft' pedals. It was played by the 1st Duke's wife after they bought Apsley House in 1817...
