[3] On 20 May 2006, in the grand final for the Eurovision Song Contest, Lordi performed "Hard Rock Hallelujah" seventeenth on the evening.

The performance took place on a fairly bare stage, with banks of video monitors in the back displaying abstract images of fire, and the band in their usual monster costumes.

During the whole performance, the band members remained relatively stationary, with the exception of guitarist Amen, who hopped back and forth energetically.

The final chorus of the song had an extended pyrotechnic display, with the whole stage covered in sparks, including jets shooting from the ends of Amen's guitar and Ox's bass as they were being played, and from the two-headed axe that Mr Lordi held up above his head.

The encore performance after they were announced the winners was much simpler, as the pyrotechnics were obviously not available and Mr Lordi's wings did not unfurl.

[12] The video starts with a shy female hard rock fan walking through the corridors of a school, singing softly along to the song playing on her headset.

As the chorus starts to play, the doors to the gym are blown off of their hinges by Mr Lordi, who enters and crushes the now-screaming cheerleaders with a wave of his hands killing them.

The end of the video shows the fan, now confident and unafraid, leading the zombies through the school halls as students run away.

She stops and punches the air with her fist as the zombies rush around her towards a group of students who are trapped by the closed main doors.

Another video was filmed specially for the Eurovision Song Contest 2007 grand final opening, directed by Antti J. Jokinen.
