When Catherine Weaver offers to sing a song with Savannah, Savannah tells her that she can't sing. In reality, Shirley Manson, who plays Weaver, is a well known singer.
The song that John Henry and Savannah sing in this episode is a Scottish folk song written by Andy Stewart, titled "Donald, Where's Your Troosers?" The original song is merrier than this rendition.
This is the first of two consecutive episodes, the other being "Born to Run (2009)", named after songs written/performed by Bruce Springsteen.
