I went to a Jethro Tull concert in early 1970 at the Swing Auditorium. This was the concert I was looking forward to. I liked the songs I heard by them on the radio. I wasn't impressed. Either right before, or right after this concert I went to a Three Dog Night concert, and I enjoyed it a lot more. Maybe I just wasn't sophisticated enough for Jethro Tull
