Koffman's 'Days gone by' reinvented into Scott's 'Slowly Surely'

Canadian jazz musician and composer Moe Koffman, was notably not a jazz purist. It is written (wikepedia.com) that his ability to change styles made him the scorn of his peers. But perhaps it was this flexibility and diversity that truly inspired the samplng of his 'Days gone by' in Jill Scott's 'Slowly Surely'.
