I was surprised to find out this morning that it's still possible to apply for tickets to the Strictly live shows. On closer inspection, I discovered that the programme is again going to Blackpool on 20th November, with all the other shows being at TV Centre. Obviously, there are going to be many more applicants than there are tickets so it's all done by means of a random draw.
A full list of all the dates, and all the details you will ever need can be found here. The deadline is 10pm on Thursday and you can apply for as many dates as you can manage, but, if you are lucky enough to get tickets, it will be for one show only.
