"sooprpig told me that music here tonight is most likely an original song made by peter for the band. he also wrote 2 other songs, "miss lucky" and "engel der musik" he was going off the discogs info, so i think it's most likely all correct.
From what it seems, the band may not have had a consistent line up, and had lots of guests/features. Also, apparently it wasn't rare for cover bands from the 80's to mix in original songs with covers sometimes. So i'd say it's all true..."
