What can be used in the place of cherry liqueur?

For alcoholic substitutions, (some may alter the "cherryness"slightly):

Cherry Schnapps, creme de cassis, Chambord, black raspberry liqueur, cherry grappa, cherry wine mixed with simple syrup, vodka and cherry syrup

For non-alcoholic substitutions, (again, some less cherry-like):

cherry syrup, cherry flavoring plus simple syrup, cherry juice and simple syrup, frozen cherry juice concentrate (undiluted), liquid from a jar of Maraschino cherries, hard cherry sugar candies (e.g., lifesavers) dissolved in boiling water and liquid reduced to a syrup
