John,
There were 61 rules in place to run the whole "AA is everything to everyone" AA club, which was an ambitious experiment in early AA. Rule 62 was basically an admission that anything that took 61 rules to administer is too damn complicated.
I have never seen a list of those 61 rules.
It was from this misadventure - and others - that affected the writing of AA's 4th tradition. This thread covers it pretty well but it is a 2 year old thread and some of the links are bad.
