Just got back from Six Flags, New Orleans. They had a decent Karaoke show considering it was an outdoor venue smack in the middle of a huge amusement park.
Appears to be permenant show with regular hours hosted by Six Flags staffers.
They had 4 Peavey Impulse 2X15's flown 20 feet up over the stage and decent 2 way Peavey monitors on stage. Couldn't see their CDG players, but they had a really nice rack-top Mackie mixer. I had to stand rather far from their stack, but I could make out a dual 31 band EQ and what appeared to be 5 mic pre's. their other gear was just too faraway to deterine what it was.
We stayed two days, I got sunburned and peed myself on the Batman ride.
It was great to see karaoke considered part of such a popular place!
