You immediately get a sense that what you are about to see is going to be special when you turn up and the whole front of the venue is obscured by a mass of people eager to get the night started. The majority of the crowd are in the same age bracket and most likely have followed the progression of Jethro Tull across the 46 years they have been playing. There are only a few of the younger generation present and they have probably been brain washed over the years by parents who are avid Tull fans.
