Eastern Time,[14][15] MTV was officially launched with the words "Ladies and gentlemen, rock and roll," spoken by John Lack and played over footage of the first Space Shuttle launch countdown of Columbia (which took place earlier that year) and the launch of Apollo 11. The words were followed by the original MTV theme song, a vivid rock tune composed by Jonathan Elias and John Petersen, playing over the American flag changed to show MTV's logo changing into different textures and designs. MTV producers Alan Goodman and Fred Seibert used this public domain footage as a concept;[16] Seibert said that they had originally planned to use Neil Armstrong's "One small step" quote, but lawyers said that Armstrong owned his name and likeness and that he had refused, so the quote was replaced with a beeping sound.[17] A shortened version of the shuttle launch ID ran at the top of every hour in different forms, from MTV's first day until it was pulled in early 1986 in the wake of the Challenger disaster.[18]
