I've tried Googling "wedding procedure," "wedding protocol," "best man's role in weddings," and "1960's weddings" (in case the time period might have some bearing on it), but nothing has told me whether this particular point is pretty much set in stone or not.
ETA: The denomination in question is Lutheran.
ETA 2: Thanks to everyone for the advice. It looks like most Lutheran ceremonies do include a ring blessing, but it also looks like it's not mandatory. I think I'm going to have my bride and groom ask not to have it included. Thank you all, again!
