Really? Why don't you explain to me, objectively and using proper musical terminology, why Yub Nub is a "horrible song". Keeping your own opinions and preferences to yourself, tell me why Yub Nub fails as a piece of music and why it doesn't work as the closing piece to ROTJ. I'll be over here holding my breath.
It works as a closing piece to RotJ, but in my opinion, it doesn't work as a closing piece to the saga. Fortunately George felt the same and changed it.
Lucas WAS heavily involved in ESB, but, he did not direct it. He handed those reins over to IK. I think Lucas is best (like most of us) when he collaborates more with others. Hence, Raiders was him and Speilberg. ESB, him and Kersh. ANH, him and Gary Kurtz. I think the prequels suffered from the lack of collaboration. Even one of the best scenes in ROTS was with input by Speilberg (Yoda vs. Palps).
