[Glockose]

Does anyone know of a 1980 demo (3 song)
It's not listed on Encyclopaedia Metallum but I have the 1987 demo with a letter from the band where thay talk about it and record the 3 songs from 1980 on the side B.


I don't know if it ever even came out as a real demo or not

Any infor would be great
