Martin Barre's electric guitar playing has been so integral to Jethro Tull's sound for so long. Has he left the fold for good?No, no! There are just a couple of projects that Martin wanted to do on his own. I told him that I think it's good to crack on and do it before you get too old. So this is just one of those years where it's good for Martin to go off, do some other projects, work with other projects and have his own identity. It's not that he's been put to one side or dismissed forever.
