 On 25 October, at King George's invitation, the children played at the celebrations marking the fourth anniversary of the king's accession.Their next public appearance was a concert on 21 February 1765, before a moderate audience—the date clashed with a Bach-Abel concert.Only one more London concert was given, on 13 May at Hickford's Long Room, but between April and June members of the public could go to the Mozarts' lodgings where, for a five shilling fee, Wolfgang would perform his musical party pieces.
