The song is ABC by Jackson's Five (really!) and the "woman" that sings is no other than Michael Jackson. Incredible but yes, it singed like a woman when he was a kid.
Here is the sample:

Part of the chorus:
"A B C , It's easy as
1 2 3 , as simple as
Do re mi, A B C, 1 2 3
Baby you and me girl
A B C it's easy, it's like counting up to 3
Singing simple melodies
That's how easy love can be
Singing simple melodies
1 2 3 baby you and me
Sit down girl, I think I love ya'
No, get up girl, show me what you can do
Shake it, shake it baby, come on now
Shake it, shake it baby, oooh, oooh
Shake it, shake it baby, yeah
1 2 3 baby, oooh oooh
A B C baby, ah, ah
Do re mi baby, wow"
Byye!!
