Leonard Cohen's great song 'Hallelujah' has taken on a life of its own these days. It's likely you've never hear his version because so many people have performed it since!
Here's a young artist who performs as Cloverton with a version of the song that features Christmas-focused lyrics.
Incidentally, it is suggested that Cohen wrote over 80 different verses for the song. Due to his Father being a Rabbi, and his strong religious upbringing, he said it was impossible to stop writing verses once he got started. When he recorded the song originally, many years ago, he did not use the same verses of the song so often recorded by KD Lang, and others today.
