I used to watch their variety show in the early to mid-70's (who DIDN'T have a variety show back then???). Anyway, I knew who Tony Orlando was (obviously), but which one was Dawn? Why didn't the other chick rate name recognition???
My favorite songs were "Knock Three Times", and "Tie a Yellow Ribbon" (a song about a prisoner wondering if his girlfriend would take him back after he was released. Gee, who wouldn't be waiting????? And, we never really knew what he was incarcerated for...).
It's interesting to note that their initials spelled 'TOAD'.
