I work at a TV station here in the US, and today I noticed a prefeed of Access Hollywood with a feature about the making of the Pepsi spot. It was several minutes long, and is probably scheduled to air tomorrow (not sure).
Roger and Brian are in the background, but it never mentions them, other than the spot uses "the old Queen hit." The feature mentions how it is rare to have so much hoopla and a party around the release of a commercial.
