I can't think of a better group to take on Grim Grinning Ghosts! The BARENAKED LADIES have this sense of style and fun that they put into their music and their arrangement of this song is perfect!
The song, written in 1969 and originally sung by the voice of Tony the Tiger, Thurl Ravenscroft, has many verses and can be heard in its various incarnations throughout the 13 minute Haunted Mansion ride at Disneyland.
The Haunted Mansion was in planning stages when Walt Disney died and changed drastically after his death so he never got to see the final results or hear this song. As one of the better attractions in the park, I think Walt would have been happy the way it turned out.
Yeah, from the moment you step into the elevator room. That's about five minutes. And you don't hear the song then. I guess I was a little misleading in my post.
By the way, Thurl Ravenscroft wasn't the only vocalist; the Grim Grinning Ghosts was originally performed by the quartet The Mello Men. I don't have the other three names handy, unfortunately.
