The event sheet is working fine. For instance, if you put your play event in the "On start of layout", you'll see that the song plays normally.
I modified a little bit in your project, see this:

The problem might be that you put a lot of pins in a lot of places. I put them only in the "on start of layout" and it worked.
I hope this helps. I guess you want a pendulum movement in your chain.. you might want to use the sine behaviour and change the "movement" to "angle". I don't know how to do it exactly, but there should be a answer in the forum (:
