I was 15 and living in Mankato Minnesota. The choice was Jimi Hendrix or The Doors, both were playing a week apart in Minneapolis, a ninety minute drive. We chose The Doors and my parents drove the four of us to the concert. The local group of Koerner Ray and Glover opened the show. Tony Glover played his harmonica with The Doors on 3 songs/jams. Great first rock concert.
