Chris McGregor, the famous jazz musician, who was the great grandson of the Reverend Andrew McGregor.

The great grandson of the Reverend McGregor was the famous jazz musician, Chris McGregor, who is credited with discovering the black jazz scene (or, more correctly, bringing it to a wider audience). McGregor moved from South Africa to London in the early 60's, along with his hand-picked band, TheBlue Notes.

The Brotherhood of BreathHis later band, The Brotherhood of Breath, is described on the BBC site as "one of the few big bands that have really mattered in the wake of Ellington and Basie", and "Under McGregor's leadership this group of disparate talents created a vibrant, distinctive music that blended township rhythms with the fire of free jazz blowing and the irresistible swing of Ellington and Fletcher Henderson".
