The album was supported with the single "Forget Him" (Chinese: 忘記他; Jyutping: Mong Gei Taa), which was written by Hong Kong media personality James Wong Jim.
Irreconcilable was commercially successful after its release, receiving a platinum certification by the International Federation of the Phonographic Industry Hong Kong (IFPIHK) in 1981.
Fifteen years later, the "Forget Him" was covered by Shirley Kwan, as part of her 1995 tribute album EX All Time Favourites.
This new Dream pop version was featured in Wong Kar-wai's art house movie Fallen Angels (1995) as the Jukebox song number "1818."
As the title suggested, the hitman played by Leon Lai wanted his accomplice, Michelle Reis, to forget him.
