Aye, tis a good disc to have. The looks I get when I'm listening to are always priceless, 'specially when I'm singing along. Got mine on e-bay. There are actually a few different versions. One was an exclusive for the 30th anniversery of the ride. The other is one you can make at the park with selections from any of the rides. Keep a weather eye on e-bay, one pops up every now and then. If you have any problems finding it let me know.
I be willing to share, I be.
