Turning up as homeless itinerant performers, they developed their concept of Situation Art while performing in cafes from town to town and performing on trains between different towns - and performing in railway station cafeterias, ticket-halls and trams. The Leuven University newspaper VETO wrote in their early days there, about the situation art of Bongo and Extremely.
But years later Belgium chose to turn against situation art - regardless of the fact that Mike and Jeremy had originally been inspired by being there to create and develop the ideas of situation art.
As mentioned elsewhere, licensing schemes were used as an excuse to stamp out street and terrace performances.
The best place in Belgium that the musicians had found where situation art could be performed for substantial continuous periods - the Brussels Metro - was taken over by a reign of extreme violence carried out ostensibly by the Metro police against performers, justified by a purported invasion of romanian gipsies; a vicious turnaround from the days when metro train drivers would stop their trains as they pulled into a station to greet Bongo Mike and Extremely Frank if they saw them on the platform, waiting to board the train to start their performance on a carriage.
The various other more occasional performance situations mentioned above were likewise stamped out, maybe as a result of the new idealism of the Super Europe, as some people have suggested... or maybe not.
Eg Leuven station, which having earlier been a good place for ticket-hall performances,
got rebuilt in a new modernistic way,
and in the process had its situation art potential designed out.
Yet situation art is itself a new arrival on the artistic stage.
