The Band World is Shocked by His Loss. We respect The Legend and his Legacy. Dr Greggs was one of the Founders of what we refer to today as The Show Style" Marching Band an Innovator of our craft I'd even go as far as to say the architect of it all. I really don't have words to say beyond that. My Condolences to the Greggs family and to the Human Jukebox & Southern University.
