Based on the song Rock'n'Roll Queen by The Subways.
A cover of this song was played by guitarist Lt. X when he asked out his lover, when he was standing in the middle of a circle with Horatio the guitar. Lt. X asked his lady if she would be his "Lil Rock'n'Roll Queen." and then he played the cover for her. She gladly accepted.
"You are the sun, you are the only one. My heart is blue, my heart is blue for you," The Subways - Rock'n'Roll Queen.
