New Apps Allow You to Become Part of Music Videos

Apps allow you to sing with the superstars.

— -- Imagine getting to perform one of music's most iconic songs with some of the world's biggest stars, all for a good cause.

That's the idea behind a new star-studded video version of John Lennon's classic anthem "Imagine" released Thursday as part of renowned children’s rights organization UNICEF’s "Hashtag Imagine Campaign."

"We are honored to highlight the challenges that face children," Jackman said at a UNICEF event.

But the really cool part? You can insert yourself in the video, using the app "Touchcast," and the final version will air on New Year's Eve.
