Hallelujah by Muttis Kinder

[HelenOE]

I think the essentials of this a cappella cover of Hallelujah are pretty well covered in the YouTube video description:

Spät nachts.
Erst Hotelbar.
Dann Hotelbett.

that is:

Late at night.
First hotel bar
Then hotel bed.

Two young men, one attractive young woman in a skimpy black dress and two mugs of beer on a hotel bed doing Hallelujah. And yes, the mugs of beer had a pervasive influence on the performance.
