Kino Lorber 4K Blu-ray disappointing

R1 DVD sounds best and has the original mono and a Dolby Stereo remix

Arrow 4K Blu-ray

Arrow 4K Blu-ray > Shout Factory 4K Blu-ray (small caveat to both UHDs: the original song The Damned - "Dead Beat Dance" has been replaced by Straw Dogs - "Young, Fast Iranians" over the end credits in the print made available to Shout Factory/Arrow) (caveat for Arrow: missing the Zombie subtitles and the workprint found on the Shout Factory release)

Comparison between Arrow and Shout Factory: https://slow.pics/c/iOrdhnra

Germany NSM Blu-ray has the unaltered Mono track with Dead Beat Dance intact.
