Answer: "Come Fly With Me"
NASA has a longstanding tradition of awakening astronaut crews with a musical wake up call from Mission Control in Houston, Texas , The tradition began with the Gemini program ̵
Every now and then a space-based crew turns the tables and instead sends a mission control wake-up call instead of waiting for Mission Control to send them. The first role reversal took place on May 25, 1969, when the crew of Apollo 10, who had awakened before her wake-up call, beamed Frank Sinatra's Come Fly With Me to Earth. After sending the song, astronaut Eugene Cernan began the following exchange with Jack Lousma at Ground Control:
Apollo 10 / Cernan: Good morning, good morning! These are Tom, John, and KAT 10 Genes, which again send to the Universe from a distance of approximately 140,000 miles (1945,9020). It's a beautiful day out here and it seems like it's a beautiful day in Mother Earth. For those of you who are not just ready for work or just getting up, stand up, rotten bones! It's time for you to get up! Big day ahead! And the thought for today is: Remember, the week of the National Secretary was last month!
Ground Control / Lousma: Good morning, Apollo 10. You've managed to get up all early and thank you for your short program. And we will take due note of your advice down here. And we have some music for you.
Apollo 10 / Cernan: Wonderful, Jack. Let's hear it.
Ground Control / Lousma: [plays music Zip-a-Dee-Doo-Dah]
