There is - or was - a Rabid singles compilation that included both Ain't Bin To No Music School and Fascist Pigs. You can buy it from £11.44 from Amazon Marketplace sellers...
...but it might be worth checking out other outlets first, in case you can get it for less (mine was £1.99 from Reveal in Derby, about 5 years ago!). I linked to the Amazon page because it has the track list.
