Pete Sandberg sings on the Alien concert which seems to be a live in a tv studio setting with interviews mixed with performances.

I got an audio bootleg of Alien, 1988.06.19 Liseberg, Gothenburg, Sweden

Yes I have received a Swedish Erotica dvd from 1989-08-15. Also got an Alien DVD but the date is 1990-02-14 so newer.

Do you mean this video? If so it is from the show I saw, 13 Aug 1988. They opened for Pretty Maids and it was a full day festival with local bands and signed artists like Motherlode, Sky High and Louise Hoffsten. https://www.youtube.com/watch?v=FTz6wTpbNCU

Sorry don't have the Alien DVD. Are you sure about the date though? I saw them open for Pretty Maids in Karlskoga 2 days later, Saturday 13.08.88
