As you said in your first post people are different - I'm sure there were a lot of people who enjoyed what Russ played and more so there are people who don't really care of the origin of a record as long as it has a certain beat. But there are others who see the scene as Soul based and prefer the records they dance/listen too to have this background of Black American origin although I do think there are certain blue eyed records which would genuinely fall under the Soul feel umbrella - Dean Parrish, Gene Latter , Jason Knight , Paul Anka's Can't Help, Lynne Randell's Stranger , Larry Santos.
But then there are pop records like the aforementioned Jackie Trent and Bobby Goldsboro, Muriel Day, Eddie Regan and tosh instrumentals like Police Story and for me these are not Northen Soul records and when these type of records began to dominate certain DJs playlists a lot of people stopped attending Wigan because it no longer felt like a NS venue and had lost it's way.
I know Wigan rallied and played some of it's best tunes in the last year or so but I'm talking about a particular period when the dodgy records took over. Some people may see these records as genuine NS tunes that's fair enough - I don't.
All the best
