Direct answer: The future pop superstar who voiced Sally Brown as a child in Peanuts specials is Fergie (Stacy Ann Ferguson). Context and notes:
- Fergie provided the voice for Sally Brown in mid-1980s Peanuts TV specials, notably during the 1984–1985 period, before rising to fame with The Black Eyed Peas. This is the most commonly cited attribution among reliable entertainment histories of Peanuts voice casting.
- There are other reported names in various sources for Sally Brown’s voice in earlier decades (e.g., Hilary Momberger in the late 1960s/early 1970s), but those refer to earlier Sally portrayals, not the mid-1980s child-actor role associated with Fergie’s recording sessions. If you’re asking specifically about the mid-1980s Peanuts specials, Fergie is the widely accepted answer.
If you’d like, I can pull more sources to verify this across different Peanuts reference sites or explore the exact specials where her performance appears.
