Just a quick clarification, you don't have to ask for permission though it's generally a good thing to do. Since the page's history wasn't preserved and the attribution requirement wasn't fulfilled through the original edit summary, the page could only be attributed now (even with a large rewrite, anything based off the current diff would still require attribution) by placing a URL back to the original source or including a list of the page's authors on the article page itself. Personally, I'd recommend a complete and original rewrite, then attribution isn't an issue.
