Little known fact. The woman in the video for "Things That Make You Go Hmmm" was not the singer. She was a model they hired. The singer was really Martha Wash from the Weather Girls, but unfortunately she was considered too ... ahem ... unsuitable for a 90s video.
People were so clueless about dance music back then. I remember hearing on fm radio in 1990 that Black Box was ... wait for it ... a man! Seems the idiot radio DJ thought that there was actually someone singing "Gonna get up, gonna get up, gonna get up" rather than two Italian blokes using a Loleatta Holloway sample on loop. His 'scoop' was that he had worked out that the 'singer of this band' (his words, not mine) had been outed as a fella. His big joke was that the band should now call themselves Black Tool.
Anyway ... here's C + C Music Factory's best song.
