Norwegian trumpeter Tine Thing Helseth performed at the Trafalgar Square Christmas tree lighting ceremony on December 6, alongside the St Martin-in-the-Fields choir and the Regent Hall Band of the Salvation Army.

Since 1947 the pine tree in central London has been a gift from the people of Norway in recognition of Britain's support during World War II, making Thursday's lighting ceremony the 65th. The Lord Mayor of Westminster, councillor Angela Harvey, and the Mayor of Oslo, Stian Berger Røsland, were in attendance.

The following day Helseth performed with violinist Vilde Frang at the Royal Norwegian Annual Christmas Concert in St Martin-in-the-Fields. She was also in London on November 13 to perform at the Regent Street Christmas lights switch on.
