I don't specifically remember any northern soul being played, not that I knew what it was in 1970 but back then Tighten up Vol 2 was played on a loop by the Octopus ride when the fair visited our small town. More recently, about 12 years ago, I was in Clacton and took my daughter on a ride which was playing some fabulous funky music. The ride operator told me the name after I enquired but my daughter's demands for an ice cream made me forget before I had a chance to write it in my phone .
