Jethro Tull + special Guest Lucia Micarelli (violin) performing Nocturne and Bohemian Rhapsody (instrumental). link
Actually I dont think this is Tull in full, i.e. no Martin Barre. Ian Anderson is currently on a symphonic solo tour (I saw them several months back, and it was an incredible show). So it depends if you consider Ian ALL of Tull, or a half (as I do). Either way it's a great recording (I wish he'd played this at MY concern, but oh well...)
