Deletion of Der Grüne Wagen

Comment: The  is not met.  Most of the sources do not come close, as detail, but even references 16 & 18 fail.  16 & 18 do not make secondary source comment on the theatre group, they just list fact about the group, and the very limited comment is on the group's production.  I am looking for the most basic comments, such as "Der Grüne Wagen is old", or "Der Grüne Wagen is a good theatre company", any adjective describing the company though preferably its history, and it is just not there.  A couple of show reviews is not enough
