This year is the 40th anniversary of the original Chess album. Many people have covered this song over the years, but no one can ever beat Tommy. Always the best.
They both partcipated at the 1988 Eurovision Song Contest, Tommy Körberg represented Sweden and Céline, being canadian (from Québec), did it and won for Switzerland. Magnificient duo here.
The reason to the surprised look from Celine Dion at 1:27 was because Tommy Körberg didn't do the wailing he did just before that time mark on the rehearsals, he just marked it. Tommy told that story himself in an interview later.
