On November 16, 2003, the pair were working on the song "Do You Like Worms?" when they ran into issues reading the handwriting of its lyric sheet. Wilson swiftly phoned Parks, who he had not spoken to in years, and immediately asked what word came after "cheering". Parks asked Wilson to fax him the lyric sheet, and within minutes, Parks called back and clarified that the word was "Indians". After Wilson and Sahanaja finished their work for that day, Wilson called Parks again and had a lengthier conversation, during which Parks accepted the invitation to join the project. Parks assumed his role as the project's original lyricist, writing the words to Wilson's melodies, old and new. Some of the lyrics were written in the 1960s but not documented. Parks had not listened to any of the "Smile" music in decades. In the interest of preserving the "integrity" of their work, Sahanaja consequently took on a less active role, contributing to the discussions only when the songwriters were struggling with "how to pull something off live".
