http://www.youtube.com/watch?v=YNg7arOQoVAFun video, I'd hesitate to call this Bubble Gum, in a way, with groups like the Mamas and Papas, the Seekers, Spanky and Our Gang and the 5th Dimension, I kind of see them more like this.
From what I understand, this group was from Maryland, the two girls are sisters, one of them went on into hospital administration. Though, it seems to me, like a rather obscure song, I watched a cover version by some teenage girls in Southern California. I like this, their other songs I heard are so-so. Very vibrant.
