He's looking for the people in a picture he snapped way back in 1964 in Florida during the band's first visit to the U.S.
Starr took the picture as a car packed with teenagers passed the band on the highway. He calls it a great shot.
The picture is one of 240 photos taken by Starr that appear in his book "Photograph." It was released earlier this year as an e-book and will be out in print on Nov. 22.
It shares the title of the 1973 number one hit Starr co-wrote with George Harrison.
