The Dares Do A Digital Age Houdini

The Guinness World Records has recognized jive act The Dares for the first concert to take place simultaneously in two places at the same time. Earlier this month during the video gaming confab E3, the the band performed the theme song for virtual world Free Realms, as well as songs from their debut album. In sync with the live set, The Dares performed on stage in the 3D Free Realms virtual world, which was then in turn projected behind them on stage at E3. Does that make it three worlds at once? I'm confused...
