I had the pleasure of seeing this group live at the Hammersmith Odeon many (blue) moons ago, while I was at University in London.  (I’m not sure how I could afford the ticket, but there you go…) They were on before the Four Tops and I have to say they outshone them by far.  I still have their LP on vinyl, though they were/are known as the Detroit Spinners in the UK, to avoid any confusion with another group called The Spinners.   Whatever, this is a great song, and the video from Soul Train is a classic!
