I think you are getting Oliver mixed up with Ann Summers. From memory I think the correct spelling is Oliver Somers. As Annefair says put it in the search engine at the top of this page and you will see some results.
Not quite right. It was Oliver SOMERS on Market Street and I think it was J.j. Bradburn's sports shop that was taken over hence JJB Sports. I think J.J. Bradburn's shop could have been on New Market Street but not 100% sure.
By coincidence Gaffer a photo has appeared on Album showing those two shops. This would be later and the two end shops are John O'Niel's TV shop and Boardmans ( who also had a shop in Ashton) Brian Boardman taught me Commerce and Book-Keeping at WGS in what I believe was the first year of those subjects being taught there (1963)
