In 2008, at the age of 19, Goddard was invited to join the American progressive rock band Trans-Siberian Orchestra on their winter tour of the United States and Canada. On 29 June 2008, she featured as one of approximately 400 performers at the UEFA Euro 2008 Final, where she sang "Off the Rails" and her first single, a cover of "Speechless" by The Veronicas. "Speechless" was released through the iTunes Store on 8 August, and was used to soundtrack a German advert for Ferrero Raffaello. Goddard was again invited back to perform on Trans-Siberian Orchestra's 2008 and 2009 winter tours, and featured on their 2009 multi-platinum selling album "Night Castle", where she had a solo on "Child of the Night" as well as providing backing vocals for other tracks.
