Lost Love Montage

A variant of the "Falling in Love" Montage where the love in question is in the past. Sappy music is playing while all of the wonderful scenes are shown from the now severed relationship, as the person in question realizes how good he had it.

Contrast with "Falling in Love" Montage and Sad Times Montage. If the person has a particular item or keepsake of their lost love's that they kept, this may become a Cradle of Loneliness.

When the character watches home videos of their past life, see Happier Times Montage, which is closely related. See also Troubled Backstory Flashback.

 * Used in the film of the musical Rent during Roger's song "One Song Glory" to tell the story of his first girlfriend, April, without Mark's aside to the audience explaining their relationship.
