As of my last knowledge update in October 2023, Demis Roussos, the Greek singer known for his distinctive voice and hits in the 1970s, passed away on January 25, 2015. He was celebrated for his work in music, particularly with the band Aphrodite's Child and as a solo artist. If you're looking for more recent information, I recommend checking the latest news sources.
