"Welcome to Earth" is a song written by Delta Goodrem, Stuart Crichton, David Hodges and Vince Pizzinga and recorded by Australian singer-songwriter Delta Goodrem. The song was first performed live during the Opening ceremony of the 2018 Commonwealth Games in Gold Coast as official theme of the games. Goodrem wore a custom-made outfit designed by Zian Couture, and was supported by 15 drummers and a 72-piece choir. Immediately following the performance, Goodrem wrote on Twitter: "What an incredible feeling performing at the Opening Ceremony of the 2018 Gold Coast #CommonwealthGames! Truly honoured."
