Basically this is a cash in on a good programme. You would be better off buying it on DVD as it doesn't quite work without pictures, especially the missing words round, the film clips and (obviously) there's none of the funny pictures.
This is just non stop laughs from start to finish. Still makes me laugh and I have played it many times. Have I Got News For You is one of the great TV programes of all time and for me it's even better on CD.
