The Aussie's contest entry song “Tonight Again” — which saw him reach the top five at Eurovision- has soared to No. 2 on the Swedish iTunes chart, just behind Eurovision winner Mans Zelmerlow’s dance tune “Heroes” at No.1.
The pair could soon record a track together, with Zelmerlow saying he would like to do a duet with Sebastian, following his win.
Sweden was one of two countries, along with Austria, to award the coveted 12 points to Australia, while Australian viewers returned the favour, giving 12 points to Sweden.
Guy Sebastian's catchy tune “Tonight Again” has also reached No. 4 in the Bahamas, No. 7 in Estonia, No. 8 in Norway and the Netherlands, No. 9 in Austria, No. 10 in Denmark and No. 12 in Australia.
