My mistake. The all-female group I saw was the Simon Sisters, minus Carly, if I'm not mistaken. It was the Womenfolk who had the hit, though, if I'm nor mistaken.

I saw this group at the Bitter End, if I'm not mistaken, in early 1966. They were terrific. They had a modest hit with "Winken, Blinken,, and Nod."
