there are 8 songs on the cd "after concert show". that was recorded live in den haag 1988. here´s the link to that:

but recently ive seen that theres now a different setlist. have a look at this setlist:

and here there are 3 tracks that arent on the cd on the first link above: "instrumental jam", "people without", "still would stand all time"

why did they just cut these three songs out?

probably space reasons. are you looking for a cd of the full show?
