Christmas entertainment at Disneyland

[RStar]

I just got back from the park. Disneyland was pleasantly light (not slow like in the old days) for a Sunday night, and we were able to walk around and enjoy things like the fireworks. But I have a couple of questions:

1) We caught the end of some kind of projections and music on Small World. Any one know if this is at certain times?

2) The castle lighting and snow other than durring fireworks- anyone know the times for these?

It was a very long line for Small World, however. Perhaps everyone was there and that's why the rest of the park was managable...
