I always understood that Dave Cousins didn't much care for "Part of the Union", or maybe just the way it hijacked the image of the Strawbs (it's probably their best known song) - maybe because he didn't write it. That version of the band split up not long after.

The Strawbs seem to be pretty active - there's currently a "Hero and Heroine" (mid-70s) lineup version of the electric band which finished a short tour March 5 and will be doing another in June, and some Acoustic Strawbs dates in April and May.
