Who most commonly sang the fastest-selling single by an Australian artist as a duet?
Anthony Callea Anthony Cosmo Callea (born 13 December 1982) is an Australian singer-songwriter and stage actor of Italian descent (parents Santina and Cosmo) who rose to prominence after being the runner-up in the 2004 season of "Australian Idol". Callea's debut single "The Prayer" is the fastest-selling single by an Australian artist, held the No.1 spot on the ARIA Singles Chart for five weeks, a record for the debut single of an "Australian Idol" contestant, and was the second-highest selling Australian single of the last decade.
Predictable (Delta Goodrem song) "Predictable" is a pop rock song written by Kara DioGuardi, Delta Goodrem and Jarrad Rogers, recorded by Goodrem for her first album "Innocent Eyes" (2003). Released in the last quarter of 2003, the single peaked at number-one on the Australian ARIA Charts, becoming Goodrem's fifth number-one single in Australia. This achievement broke the record set by Goodrem for the most consecutive number-ones from a debut album; the original record was held by Kylie Minogue. Due to Goodrem's cancer treatment, she was unable to shoot an accompanying film clip; Sony used a live video to represent the song. The live video was shot at the headquarters for Channel V in July 2003.
