Because didn’t have one person singing lead so you don’t hear Mike Smith’s voice alone, but it was magnificent. IMO, the two best singing voices of the 1960s, were Mike Smith of the Dave Clark Five and Burton Cummings of the Guess Who.
Burton Cummings. A Canadian leftie who made the big bucks off the protest movements but then there was protest in most of the music back then. American Woman was too direct.
