On 22 January 2005, Jenkins sang in Cardiff at the Tsunami Relief Concert and in April and May of that year supported Irish tenor Ronan Tynan on his first US tour as a solo artist. That May she sang at Trafalgar Square to a 15,000-strong audience celebrating the 60th Anniversary of VE Day. At the Berlin stage of Live 8 in 2005, Jenkins sang the hymn "Amazing Grace", and she later helped to launch The Royal British Legion's poppy appeal at Covent Garden whilst wearing a dress made of 2,500 poppies.
