Scooby Doo and the Folies Bergere?

I know Scooby Doo solves mysteries and I know the Folies Bergere has dancers... but I had no idea what the two things had in common. The Mystery Machine was parked at the side of the hotel we stayed in looking like this...

Are you picturing Daphne, Velma or Freddie in those little feathered outfits?
When I got back I checked out the website and if you want to do the same, here it is  http://www.foliesbergere.com/
But the answer to the mystery is not nearly as exciting as actually seing the real vehicle parked nearby!!!
