After the closure of Manchester clubs like The Twisted Wheel (and The Blue Note), the soul all Nighter scene moved to Wigan after a few months at the Torch. Here the search for ever more obscure recordings became more of the fashion than the original wider known recordings.
Today Northern Soul is experiencing another revival. In the past the Northern Soul musical appeal has focused mainly upon up tempo sounds.
I suspect that as these aging fans slow down (like us older original Wheel survivors) they will 'discover' some of the slower richer soul in many an overlooked soul ballad. Slow soulful numbers were always popular in the 1960's, many of which are listed in this database.
