Playing sound when animation starts

Here’s the thing:

I got one GameObject with animation, sound and script.

Script goes:

function Start () {
	animation["Default Take"].wrapMode = WrapMode.Loop;
	for (var state : AnimationState in animation) {
    	state.speed = -1;
	animation.Play("Default Take");

So it just starts infinite loop of animation.
Now what I want to do is to play sound whenever animation starts from the beggining (loop loops).

You could Add an event to the animation at the beginning which calls a function that plays the sound.
