Disneyland has 6 cameras set up to view Disneyland and CA Adventure during the 24 hour event and Diamond Celebration. The ones on Main Street and Paradise Pier should have good views of the new parade and fireworks show and World of Color tonight.

During the day you can hear all the special announcements made to the park guests as each hour goes by for the event.

Paint The Night Electrical Parade at 8:50pm and 1:00am PST
Disneyland Forever (60th Anniversary Fireworks) at 9:30pm PST
New - World of Color Celebrate at 9:00pm, 10:15pm, and 3:00am PST (Though I currently didn't hear any sound on that camera feed.)

I haven't checked to see if WDW is doing any live feeds.
