I scored 100% but would not have known these without the 50/50 answers: Tommy James & The Shondells, Steppenwolf, The Association, Three Dog Night, The Drifters, Gary Lewis & The Playboys, The Grass Roots, Paul Revere & The Raiders (would have guessed Jay & The Americans), The Guess Who, The Troggs, Iron Butterfly, Jay & The Americans.
So I really scored 88%. Fun quiz, Nea - thanks.
