While originally composed as the soundtrack for the documentary, Little Joe: Mercury's First Steps written and produced by aviation enthusiast, documentarian, and award winning rocket modeler, James Duffy, this soundtrack was not intended for release as a compilation of instrumental tracks, however due to popular demand, this soundtrack is now available for purchase as individual tracks or in its entirety. In addition to the complete compositions composed for and mixed-in throughout the documentary, a highly requested track from the B-58 Hustler Bomber trailer has been included, Is It Really Over.
