Back in the early 1960s during the last lineup of the act (Moe Howard, Larry Fine, and Curly Joe DeRita), the Three Stooges recorded a 45 record where they sing "Happy Birthday to You" and give other birthday greetings and tell stories, meant to be given to children as birthday gifts. However, they recorded 238 different versions of it in order to personalize it based on the child's name.
Now, these were presumably all mass-produced to a certain extent, but as of right now, it appears there's only one uploaded to YouTube ("Johnny"), and only two listings on eBay ("Randy" and "Vickie"). Pictures of the discs for other versions can be found on Google Images. So would it make sense to make an article for the other versions? Based on this page, it appears the discs may have been produced in limited quantities or were overstocked, so some may actually be truly lost.
