YouTube - Northern Soul - This England
World famous Granada Documentary - "This England" Wigan Casino from 1977.
Great tracks from the off - MVP's "Turning my Heartbeat Up", but on 6 minutes in - Judy Street "What" - awesome. Tempo, vocals! Don't know anything about Northern but this is the dogs!
For laughs one minute in from the beginning theres a guy doing a spin with his eyes turned inside out! Fooked........
