The concert was recorded in Munich on 20 October 1977, originally filmed to air on the German Rockpalast TV show.
Repeated airings have led to numerous bootleg video and audio tapes of the show being available through the 1980s and '90s.
The set is not from the same tour that produced the previously released live album On Stage (which was mostly culled from their 1976 Japanese tour), but from their 1977 European tour, a few months prior to the release of Long Live Rock 'n' Roll, with a different bass player and keyboardist.
