In February of that year, Chase and his wife relocated to Sydney, Australia. In June 1973, he appeared on part 4 of a Studio One series in a competition for the 1974 Commonwealth Games pop tune. Singing the song "Games Spirit", he was competing against "The Boy From Dundee", performed by Kamahl, "Country Spring" by Larry Philip, "Take My Life" by Desna Sisarich, "Natural Man" by Bunny Walters, and "What Do You Do" by Lutha. One of the singers he was competing against, Kamahl, was singing an Anderson and Wise composition.
