John:
All the releases I regularly deal with nowadays concern dead people (mostly I deal with estates) so I am not sure that they would help you with what you are looking for, but I'll see what I can find

P.S. I've now pulled up to examples. The first, which has fairly wide scope, and appears quite effective, is from an imaging laboratory at the University of Victoria:

The other, which is my favorite, but only because of the unusual source, is from the Canadian Forces Personnel Support Agency (CFPSA)

In either case, the two critical issues are whether there is something of value given for the Release ("consideration") and whether the Release is appropriate in the circumstances, and was entered into by knowledgeable parties. In the first case, a small amount of cash or some sort of commercial or financial benefit (such as a model fee, a model credit in a publication, or promotional photos supplied, etc.) should suffice.
In the second case, if you can adapt the Release so it clearly hows the immediate intended use (e.g. in a planned advertising program for XYZ Widgets, plus any other subsequent use, for future not yet determined uses) helps to evidence the mutual understanding.
Feel free to use anything here, but I may need a waiver from you for the free advice
