New York City, 28 August 1964. Ringo with his newly returned St Christopher’s medal.

By now most of the 10,000 teenagers who packed the streets outside of the hotel were listening to WABC on their transistor radios. When WABC disc jockeys Scott Muni and Bruce Morrow asked them to sing WABC jingles as they were playing on WABC, the entire crowd was able to do so in unison.

The power of all of this was best illustrated when Ringo Starr lost his gold Saint Christopher’s medal which was attached to a chain around his neck. Apparently as he was entering the hotel, an over zealous fan inadvertently snatched it.   Bruce Morrow and Scott Muni learned this while interviewing him over the air at the hotel. WABC listeners also heard this and so did the girl who had the medal, Angie McGowan. She had her mother call Cousin Brucie that night. But, program director Rick Sklar, ever the master promoter, could see the advantages of stretching out this drama a while longer. Even though WABC recovered the medal within a few hours, Rick arranged for the girl to stay overnight, safely secluded with her mother in a hotel room while the station continued to broadcast appeals for the medal’s safe recovery. As you would expect, this became a media sensation and WABC held all the cards. By the time the following evening rolled around, everyone was listening to WABC to see if the medal would ever be recovered. Twenty-four hours after its initial loss and subsequent recovery, WABC reunited the medal with Ringo over the air. It was a publicity bonanza for the station.
