[Flash 8] Blending/Fading Movieclips

Below I have actionscript that plays movieclips in my library at random. How can I add to this to blend(fade) the movieclips into each other so that when the movieclip is done, it doesnt fade to white it simply fades/blends into the next movieclip/slide?

 
var MCs = new Array("mc1", "mc2", "mc3", "mc4", "mc5");
var selectedMC = MCs[Math.floor(Math.random() * MCs.length)];
gotoAndPlay(selectedMC+"MC");
