Purchasers of Paul McCartney's recent "Back in the U.S." concert video will get a special treat beginning Monday (Dec. 16), when Capitol launches a "secret Web site" that can only be accessed by placing the DVD in a computer disc drive. The site will sport 30 additional minutes of performance footage plus backstage outtakes not featured on "Back in the U.S."

As previously reported, the release set records for highest single-week sales and highest debut sales of a music DVD when it moved 61,000 copies in its first week, according to Nielsen SoundScan. The companion McCartney CD sold 224,000 copies to debut last week at No. 8 on The Billboard 200.

"The album, DVD, and this secret Web site are a constant memory of the tour with a built-in ticket to the future," McCartney said in a statement. "We couldn't get everything into the DVD feature and the [ABC] television special, so the idea to be able to give both PC and Apple users a 'secret' concert and more of the backstage footage is just fantastic to me."

McCartney's representatives are touting the Web feature as the first time both PC and Apple users will be able to access this kind of content, a distinction achieved thanks to meetings McCartney held with Apple CEO Steve Jobs and Todd Collart, the CEO of DVD content enabler InterActual Technologies.

"The infrastructure just hadn't been available before," Collart told The Hollywood Reporter. "But now it is, with InterActual doing the development and Apple providing the resources. Apple has been great at supporting us." A McCartney spokesperson said the special Web site may feature ongoing updates.
