Happy Birthday! I'm a Capricorn too, mine is later this month.
My first concert was also the Rolling Stones American Tour. The concert was in Nashville. Also a hundred years ago. I remember there were three of us in a little sports car with no top. It rained and we had car trouble, but we made it for the last song. My main memory of the concert is Mick Jagger blowing rose petals into the audience.
Thanks for the cointest and have a wonderful birthday!
