"One Indescribable Instant" is a song from the popular animated film "Slumbered". This song was a favorite of Rebecca Bunch, who believed strongly in its romantic notions. It was also sung by Josh's aunt Tita Myrna when she went on "Star Search" in 1984 and received 3 and three-quarter stars for her performance. She would later sing the song at her niece Jayma Epstein's wedding. It was first heard in the Season One episode "Paula Needs to Get Over Josh!". The song is track number 27 on the Crazy Ex-Girlfriend: Original Television Soundtrack (Season 1 - Vol.2).
|The song is briefly reprised by Jim in the Season Three episode “I Never Want to See Josh Again.” It was later reprised by Tucker Bunch in the Season Four episode "I'm Making Up For Lost Time" (see “One Indescribable Instant (reprise)").|
|The song is a pastiche of typical Disney songs found in their Princess movie series. The song comes from a fictional movie called "Slumbered" which possibly is related to the classic fairy tale of "Sleeping Beauty". The name of the film is similar to the 2010 Disney computer animated film "Tangled" which is a retelling of the Rapunzel story. The love song of that movie is "I See the Light" which thematically is similar to "One Indescribable Instant" in that it's about experiencing a specific moment that changes a persons life forever.|
|Actress/singer Lea Salonga who performed "One Indescribable Instant" also sang the the love theme from the 1992 Disney animated film "Aladdin" called "A Whole New World". The "Arabian Nights" theme of Jayma Chan's wedding on the show was a direct reference to Salonga's connection to the Disney movie.|
