Radio Luxembourg DJ, Stuart Henry, has set over 750 questions to test your knowledge of pop. The questions range from the dim and distant past to the present - so it's suitable for anyone from the oldest swinger to the youngest teenybopper. There's also a mystery tune to be identified.

Alex: It sounds like a pretty drab sort of program, but Bellflower has actually come up with something that can be described as good family entertainment, and not a space invader in sight - other than Boy George! The idea's very good, and there are only one or two minor problems. The first one is that the questions can't be updated and, second your answer needs to be spelled correctly otherwise you get it wrong. HIT

Alan H: As you answer the questions correctly, you're given the chance to guess another note in the mystery tune (which is played at the start of a game, once only). If you guess correctly the note's displayed on the musical score, halfway down the screen. Guess them all, and the mystery's solved. The best thing about this game is that it has nothing to do with aliens, ghosts or tanks. HIT

Alan G: What a good idea to have a computerised pop/rock quiz for a wide range. It's appeal is only limited to contemporary music fans, which should mean that most people could get enjoyment from it. The sound is a problem and makes guessing the mystery tune difficult. MISS

Radio disc jockey Stuart Henry lends his name to Stuart Henry's Pop Quiz, a program for music fans from Bellflower Software. The program is more than a simple quiz. There are 768 questions spread over six rounds and the computer chooses questions at random, Each round also has a mystery tune, and each time you answer a question correctly you have the opportunity to guess another note in the nine, The first player to guess the complete tune wins the round.

The questions start easy and gradually become more difficult, until round six provides some really esoteric teasers which will sort the genuine pop buffs from the rest of the herd. The questions cover a range of music styles, from the early 1960s, through glam-rock to punk and the new wave.

The response time for the questions and answers is fair, although it is a pity more use could not have been made of sound in the program, given that it is about music.

A fine quiz program and one that deserves to do well.

Are you ready pop pickers? Okay, here's the first question: whose real name is Freddie Bulsara? No, I didn't think you'd get it. It is, of course, Freddie Mercury. And with a name like that it's no wonder he changed it.

That's just one of the 756 questions you'll have to wrestle with if you take on Mr Henry's pop quiz. They aren't all quite so obscure as the one above. For instance, you can count yourself an utter pop music dunce if you don't know who starred in the film Summer Holiday.

The large number of questions is divided into several different quizzes, each of which starts with this program's gimmick - a mystery tune. A musical staff appears and when you get a question right you have the chance to fill in one of the notes. The only problem is that the burst of music is so short - only five or six notes that it's very difficult to recognise it.

Players must remember to be careful typing in exactly the correct answer, although what the program considers correct is sometimes a bit puzzling. I typed in The Kinks' in reply to one question only to be told that I was wrong - the correct answer was 'Kinks'.

Even though the program claims to contain 756 questions you soon find the same ones cropping up in different quizzes, which doesn't do much for maintaining your interest.

But the whole thing is well-presented in a straightforward way and there is a good cause to benefit from the sales - a percentage of the profit will go to the Multiple Sclerosis Research Fund. a charity close to Stuart Henry's heart since he suffers from the disease.
