To be fair to XFM, going by your post, it did do what it said on the tin....
"Northern Soul with Russ Winstanley
Join Russ every Sunday as the Godfather Of Northern Soul brings stories, memories and spins the best classic cuts."
stories, memories and spins the best classic cuts........ sort of gives it away really doesn't it , the show is meant to be nostalgic, personally having read the blurb it would of convinced me not to turn on as it was obviously going to be the same old RW self adulation and twaddle, far better radio shows to tune in to on a Sunday night
