Who's more embarrassing? The guy in the uniform who wrote and sings lyrics to the Deep Space 9 theme song, or the guy who knows that Gene Roddenberry did in fact write lyrics for the original show's theme song?
We may know that he did write lyrics but we didn't try to remedy the situation of a theme song less show by giving a song lyrics when it clearly didn't need them. Also these are the most asinine and stupid lyrics. He says "Not Deep Space Eight" and he's not being sarcastic about the lyrics, you'd think that someone like him would know about comedy music, or at least Filk music. Or at least music, which I'm starting to doubt he's ever heard of.
I stopped the video at that point thinking to myself "I swear the sheet music for the TOS theme had lyrics on it." Well what have we here: http://www.snopes.com/radiotv/tv/trek.asp
