I'm defining "solo" as a song where the character either sings an entire filk alone, or with a chorus. If with a chorus, the chorus only repeats what the soloist has already said (excluding appropriate change of pronoun) without adding new material (e.g., some of the "Major-General" parodies). Also permissable are interjections from a second character, if all of the second character's lines are spoken rather than sung.
