The Lovin' Spoonful, so much fun, harmony and melody in music such as:
"Bald headed Lena has anybody seen her?
Cute as she can be
She don't wear no wig
Her head's bald as lead
She's all right with me..."
And:
"Everybody knows that the very last line
Is the doctor said
Give him jug band music
It seems to make him feel just fine"
And Zally and John could really play their guitars, no Wrecking Crew needed here like every other band (even the Byrds) of those days :)
