Mozart, the boy wondered, enchanted anyone who was everyone from noblemen to royalty. Leopold revealed his attention and was also no doubt grateful for the hard cash produced by his offspring. The King presented him with music from Wagenseil, Bach, Abel and Handel and at first sight he played them all. He played the King's own organ so well, that people said that playing his organ was better than playing his piano. He then accompanied the Queen in a poem, and the flute player in a piece of flute and piano.
Leopold moved his family to recover from a chill and sore throat caught at an open-air concert at the house of the Earl of Thanet in Grosvenor Square, here on 5 August 1764. A blue plaque commemorates their stay. Mozart wrote his first two symphonies, K16 and K19, to keep himself busy.
