Trivia: One of the cutaway gags is about someone who survived 9/11 because he was late for work watching late night football. Seth MacFarlane missed his flight, which would have been one of the flights to crash into the World Trade Center, because his agent had given him the incorrect departure time. The plane was scheduled to depart at 7:45 AM and his agent had told him it was departing at 8:15 AM. By the time Seth arrived the boarding had been closed and he was told he would have to catch a later flight.
Chosen answer: It's a real song called "Elvira". Originally by Dallas Fraizer in '66, however, this version seems to be the Oak Ridge Boys cover version. However, the mega lesbians skip the verse and just sing the chorus after the opening line.
