who wrote the song this i promise you
This I Promise You The song was composed by pop singer Richard Marx, who would later record the song twice, first for the Japanese release of his album Days in Avalon similar to the NSYNC version, and again as a rock song for the European version of his Stories to Tell album. Marx would later use the Days in Avalon version of "This I Promise You" for his Now and Forever: The Ballads album as a duet with Asian singer Sabrina.
