Why wasn't Paul McCartney featured along with the rest of the Beatles on Helen Shapiro's video Look Who It Is?

Paul McCartney was not featured in Helen Shapiro's video "Look Who It Is" because he was ill at the time of filming. The rest of The Beatles—John Lennon, George Harrison, and Ringo Starr—were present and performed in the video, but McCartney's absence was due to his recovery from a mild illness. This led to his being replaced by a stand-in for the performance.
