I've played Charlie Brown on several occasions and, although it's one of my favorite shows to perform, it never really sells well unless it's done for a kids' company as most people (at least 'round these parts) hear the name and immediately consider it Children's Theatre. Same goes for "Seussical" (which is another favorite of mine!)
If you're looking for a money-maker with room for a chorus, this show probably isn't for you.
On the up side, though, it's relatively inexpensive to produce, i.e. sets and costumes.
Having done the original, the revival and a mish-mash of both (oy!) I'd have to say that the original has more charm, while the revival is more upbeat and fun. It all depends on what you, your company and their audience prefer.
Hope this helped!
