The Beatles concert in Philadelphia was sponsored by WIBBAGE radio. The month before the Beatles came to town, the radio station ran a contest and 9 girls were chosen (9 because of the call numbers 99 of the station) to meet the Beatles live and in person at the press conference before the show at the Convention Hall! How exciting for those 9 lucky girls and how disappointing for the thousands who tried to win and didn't make it.
If you live in the Philadelphia area, you might want to check out the Broadcast Pioneers luncheon on Wednesday September 17, 2014. One of the girls who won the contest is going to be speaking, along with Larry Kane and a group of former WIBBAGE disc jockeys. They will be talking about the Beatles concert. Sounds like a fun time! http://www.broadcastpioneers.com/
