Kofi and the rap battle summer

Kofi is a natural entrepreneur, and is always quick to spot a moneyspinner. But what he had overlooked is his best friend's Kelvin's amazing photographic memory - and the fact that he can remember every single line of a song he's heard only once. The whole school is obsessed with music, and no one can ever quite make out the words of the songs, so Kofi spots a golden opportunity to sell a fanzine packed full of song lyrics. But it doesn't make him popular with all the teachers, and along the way, he gets caught up in several false starts, a slot machine scam, and detention, again.
