Space Cadets is a British television programme made by Zeppotron (a division of Endemol UK) for Channel 4. Presented by Johnny Vaughan, it was aired across ten consecutive nights beginning on 7 December 2005, with the final episode aired on the evening of 16 December 2005.
Johnny Vaughan was not born yet in 1967.
There isn't really anything in the text to suggest or disprove that he was not alive yet in 1967, so we don't know for sure. It's difficult because the system consistently struggles with questions asking about existence when dates are mentioned in the text.
