Terrible echo in here.
The Critics weren't a "group" in the beat combo sense.
Their name stemmed from the concept that they worked together in the spirit of self criticism.
Where they did this was in England's majot cities, i.e. (principally with MacColl & Seeger in London, Harry Boardman in Manchester and Roy Harris in Birmingham).
They were scarcely unknown to each other.
As has been mentioned before, it's all there in some detail in Harker's bio.
