How to put a loading animation between scenes

Question

I wanted to put a loading animation between scenes. I have used

[[CCDirector sharedDirector] replaceScene:[CCBReader sceneWithNodeGraphFromFile:@"SongScene.ccbi"] ];

for load the second scene.First scene is a kind of song selection menu. It takes a little delay to load the SongsScene because of the graphic loading time. Then user is not noticing whether the scene is loading or not. Is there a way to display animation while the second scene is loading.
