The last track on the album was originally scheduled to include a saxophone part recorded by astronaut Ron McNair on the Space Shuttle "Challenger", which would have made it the first piece of music to be recorded in space. However, on January 28, 1986, 73 seconds after lift-off, the shuttle disintegrated and the entire "Challenger" crew were killed. The track was dedicated to McNair and the other astronauts on board "Challenger". On the album, the saxophone part is played by saxophonist Pierre Gossez.
