BB appears to have been a DIY label; the only record that I have seen on it, 'Disco Light Shuffle' by Nottingham band Rits, was made by custom recording firm Tank Records, of Warwick. The catalogue number of that single was BBR-7901, its matrix number BSS-361, and it was issued in 1979. According to Robert Bowes, who kindly drew my attention to the label and supplied the scan, the music is a fusion of Punk and Disco. There is an article on the band at the Tamworth Bands site. The link comes by courtesy of Steve Mitchell of the Low Down Kids site.
