Conversation so far:
Did the band reunite during this time frame?
In 1990, the former line-up of van Leer, Akkerman, van der Linden, and Ruiter reunited for the first time since 1975.
Did anything particular happen during the reunion?
The four played a 40-minute set at the Americahal in Apeldoorn on 20 April that was broadcast as part of the Oud van Goud television special.

Question: Was there anything else important happening?
Self-contained rewrite: Besides Focus playing at their reunion, was there anything else important happening?
