I expect a rant rather than any kinda debate judging by this "review" but thar ya go? I didn't think that 'Northern Soul' as it became was around in 1966? Unless you call being a Soul Fan & from the North [as I am too!] in the 60s being classed as "Northern Soul". However the genre wasnt established, as I remember till the much later 60s/earlier 70s - & yes, course a lot of the discs - as the genre grew rapidly - were 60s tracks.
All-nighters' timing depended on where you went e.g. Palais in Nottm went from 12-6 or 8am & differed as did Colemans who I cant remember doing as many but admit I may be wrong there?
As for our precious 'Casino' [loved Blackpool's Mecca myself but, again, its up to the individual anyway/anywhere] remember hearing of a lot of bland pop music being played there e.g The Dooleys [heard on my 1-&-only visit] & er, Barry Manilow's Copacabana [as did Colemans the latter] cant remember what 'Casino' DJ said to the effect that if it had "the" beat - it'd be played..by way of an explanation!?! I didnt take drugs but if I heard that regular - I might've needed 'em too???
Much of what you say could possibly be challenged by Soulies from different Northern towns so maybe you shoulda took a chill pill [oops bad choice of words..] & just enjoyed a trip down someones Memory Lane with a fair soundtrack - if you want badly produced garbage from someone with his own ideas of recreating the scene of 'back in the day' [BADLY!] then get anything produced by Ian Levine! Then you'll be really scraping the "tripe" barrel!!! Have A Good 'Un & KTF!
