I appreciate a lot Bruno's investigations but I get lost very early...
Is there any conclusion?
The other conclusion is that the bootleg Once upon a time in 1983 XX.XX.83, which until then, its date and location were a mystery, is a strong candidate to be the real 30.05.1983 Centre Sportif Differdange Luxembourg, the recording has all the characteristics of the tour period between 24.05.1983 Hallenstadion Zürich Switserland to 12.06.1983 Ijsselhal Zwolle Netherlands
Thus, it could be the following dates not yet catalogued:
25.05.1983 Patinoire des Vernets Geneva Switzerland
26.05.1983 Patinoire des Vernets Geneva Switzerland
27.05.1983 Palais des Sports Grenoble France
28.05.1983 St. Jakob Sporthalle Basel Switzerland
30.05.1983 Centre Sportif Differdange Luxembourg
01.06.1983 Forest National Brussels Belgium
12.06.1983 Ijsselhal
