twinkle twinkle little star

in 1990 I bought a baby lullaby cassette set from Costco. The music was beautiful along with the voice that sang the songs. The packaging was yellow, with baby pink and blue.
I cannot find the specific sounds and voices on itunes. I've been looking for a couple of weeks now, and cannot find the same artist. Even though I don't know her name, I would know her voice if I heard it. Does anyone know this cassette?
