I just saw Jethro Tull's fantastic show at the Kodak Theater in Hollywood (sold out with 4,000 people, which pleasantly surprised me). They're playing about half of Bohemian Rhapsody, and guest violinist Lucia Micarelli (www.luciamicarelli.com) plays Brian's guitar solo (before the opera section) on her violin. I'm not sure where exactly the song starts, but it ends where the opera section would begin. Then I think it went into Kashmir by Led Zeppelin.
Tull's current setlists are here: http://www.tullzine.org/2005revs.htm

Ian Anderson is another one of those fun, energetic types of frontmen so many of us tend to like ;)
