2260: B & B

One clue lacks a definition part; its answer is a film title. One unclued light (three words) is the title of a song in the film, and one unclued light (two words) is the name of its singer. The first word of the song’s title defines three unclued lights, and its third word defines three unclued lights. Ignore an accent in one unclued light.
