I went to see a movie the other day and saw the new Playstation commercial, which just so happened to use a circus-type of song! It's called Ladies and Gentlemen by Saliva, from their new album "Blood Stained Love Story". It's a song similar to Christina Aguilera's "Welcome", with a showman or ringmaster hyping the audience for the upcoming show- and it rocks pretty hard!
Ladies and Gentlemen by Saliva [Official Site] [Lyrics] [Music Video]
Ladies and gentlemen please
Would you bring your attention to me?
For a feast for your eyes to see
An explosion of catastrophe
Like nothing you've ever seen before
Watch closely as I open this door
Your jaws will be on the floor
After this you'll be begging for more
Welcome to the show
Please come inside
Ladies and gentlemen
