We thought : lack of Oxygene 1, as an intro, could have been left, because of public transport.
It does sense : concert started at 20:15, ended at 22:15...after 22:30 (but mainly 23:00), there are indeed less buses, trams or metros!
So : really, 1-2 more tracks and we didn't catch "any" buses or metros.
Anywaaaaay...
Classifying the concert from scale 0 - 5 : 4,5 !
