Eduard Anatolyevich Khil (Russian: Эдуард Анатольевич Хиль; 4 September 1934 – 4 June 2012) was a Russian baritone singer and a recipient of the People's Artist Award of the RSFSR. Khil became known to a western audience in 2010 when a 1976 recording of him singing a non-lexical vocable version of the song "I Am Glad, 'Cause I'm Finally Returning Back Home" (Я очень рад, ведь я, наконец, возвращаюсь домой) became an Internet meme, known as "Trololololololololololo" or "Trololo".
In late May 2012, Khil suffered a stroke and was hospitalized with serious brain damage, where he fell into a coma immediately afterwards. His condition was later reported as critical, with irreversible brain damage. Doctors were initially optimistic about a partial recovery, but later retracted these statements. He died in the hospital in St. Petersburg on June 4, 2012, from complications from the stroke, aged 77.
