One event, two actions?

Should be simple, but can not find the way to write 2 actions triggered by 1 event.
I have:

band_btn.onRelease = function () {
loadMovie("clip_a.swf", "_root.clip_on_stage");
}

and need also this button to do this as well:

band_btn.onRelease = function () {
gotoAndPlay(1);
}

I tried and both work separately, not together.
Thank you for sharing.

Chris.
