April come she will--simon & garfunkel

 April come she will
When streams are ripe and swelled with rain;
May, she will stay,
Resting in my arms again

June, she′ll change her tune,
In restless walks she′ll prowl the night;
July, she will fly
And give no warning to her flight.

August, die she must,
The autumn winds blow chilly and cold;
September I′ll remember.
A love once new has now grown old.
