Charted at #43 on Billboard Hot 100 in December 1964. In 1964, many were trying desperately to ride the wave of the British invasion. Four Italian guys from Brooklyn came up with an idea. What if they wore masks while performing, tried to sound as British as they could and called themselves the "You Know Who" Group? Maybe people might think they were a famous British group! Everyone tried hard to keep their identify a secret. It wasn't until some 50 years later that one of the group members told the story of how they came to be. This was their only Hot 100 entry, but it did fairly well, even charting in the Top 10 locally in some areas! Since the Beatles were famous for their "yeahs", this group made sure to include a fair amount in their recordings.
