Nothing at all Ian, and I know your taste in music is amongst the broadest I know.
I just don't 'get' the connection with R&R and C&W. For me soul started in the early 60s - Money, Chuck Jackson, etc, and northern sounds really around 64/5. It developed in part (but not exclusively) from R&B - but that doesn't mean I have to like R&B as someone on here implied yesterday. As it happens I do like some, have just got a minty London copy of "The Walk" for example - great song. But then again I also like Bull Moose Jackson "Big 10 inch" Kip Anderson, and a host of other not really soul R&B records. Undoubtebly Randy was to blame for putting me onto these types of records But all joking aside, I wouldn't want to hear them at a nighter. Anything before the mid 60s doesn't really fit my personal description of northern soul. At the other end whilst I like a bit of soulful house I don't think that either would fit into a niter environment well.
Whilst I don't like R&R I do respect those that have kept the torch of that genre shining. Thing is those guys don't rate the records that have crossed over to the northern scene. Geeselad charitably described it as "tin pan alley", I think some of the genuine R&R guys wouldn't be quite so complimentary.
I just sense that as we evolve, the types of sounds played at the venues will losen somewhat to be more of a 'bit of everything' whether that be northern, funky northern, xover, midtempo, kick ass uptempo, uplifting gospel and beyond. And whilst Peter S might fire off objections from behind his computer screen, as a self confessed "non attender", I am sure that his views will be drowned out for the most part by good quality music.
