Stock Photo - This on-stage shot reveals a very musical scene inside Houston's Jones Hall, as the Irish band Chieftains joined with the Houston Symphony and other musicians during the band's Feb. 15 stop on its 50th anniversary concert tour. NASA astronaut Cady Coleman, frame center, whose 2010 stay aboard the International Space Station provided some special bonds with the Irish group, was joined by NASA astronaut Dan Burbank, seen in NASA flight jacket dancing on stage, and a pre-recorded message from Canadian astronaut Chris Hadfield, now serving as a flight engineer aboard the station, in performances during the evening's celebration. Hadfield's appearance onboard the orbital outpost was shown on an elevated screen (out of frame) in the Hall.
