Here’s a video of Buzz Aldrin, the second man to walk on the moon, singing “She Blinded Me With Science” with musician Thomas Dolby. Need some context to enjoy this odd astronaut duet? Read on.

The performance took place during the Smithsonian’s “The Future is Here” conference, held at the National Museum of the American Indian on June 1. Other speakers included ocean explorer Bob Ballard, National Zoo veterinarian Suzan Murray and Nobel physics laureate John Mather.

Spoiler alert: The moonwalker is not a great singer. But the duet is still plenty enjoyable— and a little terrifying—so watch it below.
