No @CyberSkull.
As @mmirG said we are exactly in the case I told as argument as to not edit global artist credit for unknown:
Please cancel your edits because @mmirg said this was unknown artist(s) performing famous songs (cover band albums citing original performers).
@CyberSkull, you should not only cancel edits to this release but all edits, IMO, for the reason that the same case may occur for many [unknown]’s AC.
