Yes they are appearing in my local city in April next year.

The TV channel Sky Arts show a number of programs about rock acts (many programs about rock acts actually) and the other day they showed a 90 minute history of Jethro Tull with interviews with many of the ex band members.
Program must be a few years old as Glenn Cornick was in it (who sadly died in 2014).
It was amazing to see the ups and down the band has had since 1967 / 68 when they first began to get together, with lots of band members coming and going, some members dying, many arguments, good albums and bad albums and so on.
And Ian Anderson has been there in the centre all the time, with Martin Barre with him for a lot of the time as well.
Amazed to see David Palmer, a past band member, who was married and had children, but has now changed his sex to Dee Palmer after his wife died and he/she had gender realignment.
I think if anyone has Sky they can download the programs from the Sky Arts web site.
There is also a 30 minute "overview" of the band on Sky Arts which rushes through their career, though the big mistake on that program was saying Aqualung was a double album. Tut tut !
