I remember that there was a Co-op Dept. Store at the Big Top in High Street. It was opposite, or more or less opposite, the old Co-op which was demolished to make way for the Pavillions shopping centre. The one at the Big Top had a dance floor above it 1963/4.
Around the corner was the Odeon and a few doors away was the old Littlewoods shop with wooden floors and opposite that was the posh Marshall and Snelgrove store with a red carpeted staircase towards the back of the shop.
The "new" Littlewoods on High St. closed down and became the site for Boots which is more or less opposite where M&S is now. That Littlewoods and Boots site had previously been the home of "Henry's" store
