According to Dave Brock, speaking during the live session on the Marc Riley show, the title is taken from theSkylark series byE. E. "Doc" Smith.[10]
However, it has also been speculated and assumed[13] that the title may in reality be more directly influenced by the British Kids TV cartoon of the 1970s 'Noah and Nelly' who flew the Skylark, and used the familiar catchphrase call of 'All aboard the Skylark' in each episode.
