Just to clear everything up:
The instrument--the keyboard to be specific--that was used in this song is called the Fender Rhodes.
In fact, if you look up the credits on the IMDB page, under "Music Department" you'll find Scott Kinsey was the musician playing the keyboard on the song titled "Fender Roads."
I'm guessing it was an in-joke between the music supervisor (David Holmes), the other musicians, and whoever's in charge of naming the characters.
