I have been a fan of Jethro Tull for close on 40 years.  The band is currently on tour in Australia but before heading Down Under, Ian Anderson marked the 50^th anniversary of the Yuri Gagarin first manned space flight.  Anderson was in Perm, Russia and he did a Space Flute Duet with NASA Colonel Cady Coleman.  Here’s a link – I love the way the weightless flute drops past the flags of the world in the opening.  The piece is Bourée. http://www.youtube.com/watch?feature=player_profilepage&v=XeC4nqBB5BM
