BW labels came on the scene in November 1979. This particular BW was the record label of Brent Walker Records and Music Division Ltd, which was presumably an arm of George Walker's leisure and cinema company. It managed at least one singles on BW, the single 'I Feel Lucky Tonight', by The Stylistics; it did however come out twice, being first issued in November 1979, with the catalogue number BW-1, through Charmdale, and then again, in February 1980, with a new number (SBW-10), through CBS. Thanks to Robert Lyons For The Info.
