Meeting the Abba girls in 1979

I was 14 when my mom surprised me with tickets to the Abba concert on September 30th 1979 in Chicago. Im almost 52 now and I am a true fan. I've been to dozens of concerts but none even come close to that night. You must keep in mind the popularity of Abba then. My mom and I sat second row so I touched their hands during Dancing Queen. Since my mom was a journalist we met only Frida and Agnetha when the concert ended. Anyway I think it would make a good story
