And Then There Were Fewer - S9-E1
Character mistake: When driving to the manor, Lois wakes up and says "Peter, look" as if she knows they are there. She could have not been able to notice this since the trees are blocking all view of the manor. (00:03:00)
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.
