I remember the rumor a couple years back about music from the movies playing in the Blue Bayou. What a sickening idea. As much as I enjoy the score to the first movie--I even play it on piano--it would be so ridiculously out of place in the Blue Bayou! The alto flute rendition of Yo Ho must stay.
I don't think the Blue Bayou needs any changes, except perhaps reduced prices and a few more options. But I agree that anything with references to the movie characters would be incredibly tacky. The Bayou really isn't a Pirates of the Caribbean restaurant; it's just located in the same place.
