Number 1 Singles

[mewtwo]

I want to find all the number 1 UK singles there have been for a particular date, I have used a website before where you just typed in the date and it gave you every number 1 from 1940s to present year for the date wanted but I can't remember what it is - can anyone help?? The date I am interested in on this occasion is 11th August. Thanks
