Childhood in a Song

This is one of the songs I remember most of all from my childhood.
It makes me think of my big sister and I, dancing around her bedroom and singing along.
I grew up with a brother and sister much older than me, and my music taste was heavily influenced by what they and my dad listened to. Except, I averaged between the musical eras and my heart landed in the late 70's and 80's.
