Until IASM came along, the music from the Swiss Family Robinson Tree House was the most obnoxious in the park. You had to hear that stupid polka about 30 times while waiting in line for the Jungle Cruise. I believe the tree house is gone now. Good riddance.
In downtown Disneyland there is a violinist who plays quite well. But, it's the same performance every night. One night I was getting a hogs and dogs ice cream right next to his performance area and I asked a clerk if that violinist was there every weekend.
"no," the clerk replied, "He's here every damned night, every damned night."
That's why they're called cast members.
Re Swiss Family Robinson Treehouse: I think it’s been redone as Tarzan’s treehouse. The music is gone, though.
