Dm, Bb, F, C these 4 chords throughout the whole song you can figure it out i m sure.

The sun shines so bright today,
Head out its a hazel day,
Thats today,

Your hazel eyes they take me by surprise,
by surpise, these hot summer days,

Your brown eyes are green today,
All you need is a summer day,
These summer days,

Your hazel eyes they take me by surprise,
By surpise, 
These hot summer days,

Your hazel eyes they take me by surprise,
By surpise, 
These hot summer days,
