Former Beatles star Ringo Starr is asking fans to help him track down the Fab Four fans he photographed from a car window in Florida during the group's first U.S. tour in 1964.

The never-seen-before black and white shot is featured in Starr's new coffee table book, titled Photography, and he'd like to track down the beaming kids.

Anyone who recognises themselves or someone else in the shot are asked to get in touch with NBC news outlets across the U.S., so that network bosses can put them in touch with the photographer - Starr himself.
