"I knew Joe Robinson, owner of Sugarhill very well in the 90s and spent quite a lot of time with him and Sylvia working out of the studios in New Jersey making copy tapes for UK releases. Chess of course was long gone to MCA, but there were still a lot of tapes there as well as photos from Chess. Joe told me that all of those albums you are discussing [Blues Ball and Blue Night] and those on Le Roi Du Blues were produced by the guys who had already been producing reissues for Sugarhill and the tapes were provided to them because he could not afford to pay them what he owed them for work already done."
