There has been an OCRemix colloborative project for Donkey Kong Country 2, titled "Serious Monkey Business," going on for a while now. There have been many similar collab project in the past, including one for the original Donkey Kong Country, Kong in Concert.

Today, one of the project's leaders announced that the track "Donkey Kong Rescued," which played during the game's credits roll, has been taken by none other than the game's original composer David Wise, as well Grant Kirkhope and Robin Beanland. Kirkhope will be playing guitar and Beanland will be playing the trumpet. Very exciting news indeed.
