According to my spouse...
They are still going! I didn't see them in the UK but my OH saw them in Leeds, Bradford and Brixton!
They are touring at the moment and they have a new album coming out soon.
Their web site is slf.com
If they visit Oz again I wll certainly hear about it and put a posting on the site.
We saw Greenday at the Adealide Entertainment centre a few weeks ago...and I heard it over and over that Greenday had modelled themselves on STIFF LITTLE FINGERS!!!
