I agree totally, but at my first allnighter at Va Vas just pre Wigan, Someone(probably Dickie S) was playing "Under My Thumb" by the Rolling Stones. Oh and "That's The Tune" by PJ Proby.(and I still have the Album with it on!).
The problem was, you could cope with good danceable pop/"Blue eyed soul" being played amongst the majority of true uptempo soul. It was just that the plot was well and truly lost by about 76, 77.and to a certain extent from 74.
Oh1 and I have always loved "The Snake" since I first heard it at a youth club in 1971. The thing is, my other favourite sound at the time was "Scratchy"
