I´m pretty sure the last two notes of the recording (two firsts of a new song) are yes the Sonics but "Have Love, Will Travel", not Psycho.
By the way, the song you´re looking for could be "Night of the Phantom" by The Gravedigger V. I believe to recognize Leighton Koizumi´s voice and the song is this one i guess, or very similar... but sounds like a live recording, not the original version.

I know the Soulcat in Berlin, who was the Dj at that time?
