Curious. There's a Facebook page called "Dr. Loretta Long", which includes a link to callmesusan.webs.com ... it links to a website called "My Friends Called Me Susan". The video is legit. Thing is, that Facebook page lists the 1940 birthdate!
The new video of Loretta was uploaded to Vimeo by Scott Alboum, should we send an email to his Rider University address and ask him to ask her? I tend to think that the 1938 date must be right.
Given that this was 2007 and we were in the early days yet and not as vigilant as we are now, I wouldn't be surprised if I copied it from IMDb, Wikipedia or another biographical site, and as we know, those aren't always reliable (combined with the occasional showbiz tendency to lessen one's age, but also that of readers to take articles that say "So and so, age 60" or whatever which themselves may be off by a year and then try to work backwards).
