Found yet another version of Engel

Today I found another version of Rammstein's Engel, but this version was done by "Gregorian". So with four different versions, I would say this is second. Here is the order I would put them:

1. Rammstein's original Engel from Sehnsucht album in 1997


2. Gregorian's Dark Side Engel


3. "Engel" by Peter Schilling


4. Engel by Scala
