Mighty Wind, A Easter Egg - Hidden Menu on Guitar String

I rented the dvd once and found this easter egg by using my arrow buttons to click on the (background of menu) guitar string
- first go down a couple of options and
- hit 'right'
- until the far right guitar string is lit up
- click ok
and choose any of the items on the new menu:
the newspaper articles for "whaa happen?"
the article on the events on the night mitch was beat up at mickeys concert.
behind the scenes video of the crew shaking the hotel wall with 'mitch' in the other room (pretty funny :)
and i believe a deleted scene.
im sorry i forgot the specific way to access the guitar string - the guitar, i recall, was in the background design for one of the dvd menus and it was pretty easy to find. I will rent it again and write down all the specific details soon, if no one else can find them.
happy hunting :)
