Could children’s entertainer Raffi and astronaut Chris Hadfield sing together one day?

Hadfield was in Calgary Tuesday to talk to CBC about his new book An Astronaut’s Guide to Life on Earth.

Via Twitter, Canadian singer Raffi asked CBC TV’s Rosa Marchitelli to find out how Hadfield’s view of space has impacted his life on earth. Raffi also tweeted: “let’s sing together sometime!”

“I would be happy to sing with Raffi. That would be fun,” Hadfield said.

More than 19 million people have watched a YouTube video of Hadfield singing David Bowie's Space Oddity, recorded on board the International Space Station.
