"Spaceman" is a single by Dutch DJ and record producer Hardwell. It was released for digital download on 23 January 2012.[2] A second version called "Call Me a Spaceman" featuring vocals by Dutch singer Mitch Crown was released on 18 May 2012.[3] Another vocal version was created in collaboration with Bright Lights. Despite Hardwell claiming that the latter was his favorite, his management decided to rather release "Call Me a Spaceman".[4] Titled as "Mr. Spaceman" Bright Lights offered the track as a free download in late 2015. For "Spaceman"'s five-years anniversary he released the remastered Bright Lights version as "Mr. Spaceman (2017 edit)".[5]
A 2022 rework of the song, which had previously been uploaded exclusively on SoundCloud, was released on the deluxe edition of his album Rebels Never Die.[6]
