Amazing what you'll find when you get off your butt and do a little research. I used to watch Our Gang/Little Rascals religiously as a kid, and most of my friends did too. They're on again, broadcasting on AMC. Ellen's mom still watches them, even though Ellen thinks they're more than a little weird. I always wondered what happened to everyone, and now I've found out a bit:

Spanky, whose real name was George McFarland, was never a porn star, which was a big rumor when I was in college. After many setbacks it seems he went to work for Philco-Ford television, became an executive, and retired. He died in Grapevine Texas in 1993.

Alfalfa, whose real name was Carl Switzer, ended up getting shot and killed on January 21st, 1959 at the age of 31. The stories are conflicting, but it would seem he went the classic route of too many child actors: not being able to get work, turning to drugs and alcohol, and then ending up dead over something stupid. A more detailed, if sensational, version is here

Buckwheat, whose real name was William Thomas, stopped acting and became a Technicolor technician for more than 20 years. Nobody associated with Our Gang even knew what became of him until 1974. He died of a heart attack in 1980 at the age of 49. A nice tribute page can be found here.

Styme, whose real name was Matthew Beard, kept acting with a moderate amount of success, in later life starring in films like the "Buddy Holly Story" and doing guest spots on shows like "Good Times". He died in 1981. A good career summary is here, and an "official" website is here.

Darla Hood, who played the comic foil for most of the "He-Man Woman-Haters Club"'s antics, found work later in life as a background singer for radio programs, and eventually did voice work for commercials. She died of acute hepatitis under "mysterious circumstance" after a "minor operation" on June 13, 1979. She was only 47 years old. A brief summary of her career is here, and this site, that appears to be in Portugese, has some nice photos of her later in life. If you can get past the annoying music that is.

There were others of course, Jackie Cooper and Robert Blake being the most famous, but these were the ones I remember as a kid. The series went on for something like 22 years, so I've probably missed your favorites. The best overall site for Little Rascals information is Our Gang Online, although it doesn't look to have been updated lately.

So there you have it. "Real Hollywood Stories" it ain't, but interesting nonetheless. Enjoy!
