Bored on Saturday afternoon waitning for the rain to stop, I took it upon myself to search out printed versions of the club name on and in various places. Now, is it:

Tottington St Johns Cricket Club
or
Tottington St John's Cricket Club ?????

As you may know, the use of the apostrophe intrigues me. Mrs Hunter will be on the case, but feel free to join in the debate.
