"Archie Marries Valerie" was in ARCHIE #631-634... and later reprinted in the trade paperback ARCHIE: A Rock'n'Roll Romance (2014). That was strictly Dan Parent's idea. Neither Michael Uslan or Paul Kupperberg were involved.
I think the 10th Anniversary series was unfortunately named, since it should have been more accurately titled ARCHIE MARRIES 10th Anniversary to avoid confusing potential readers about what, exactly, it was a sequel to. Nevertheless, it seems like The Married Life from LIFE WITH ARCHIE was more likely to be a stronger draw, sales-wise, than Archie Marries as a title, and ACP chose it deliberately.
