"Jackie Wilson Said (I'm in Heaven When You Smile)" is a song written and performed by Van Morrison and featured as the opening track on his sixth studio album, Saint Dominic's Preview.

"Jackie Wilson Said" was covered by Dexys Midnight Runners on their album Too-Rye-Ay and reached number five on the UK Singles Chart when released in 1982.

[3] The first known recording of "Jackie Wilson Said" was in January 1972 at singer and musician Lee Michaels' studio in Mill Valley, California.

On January 29 it was recorded with "Gypsy" at Pacific High Studios in San Francisco for his forthcoming album, Saint Dominic's Preview.

Morrison was joined by his band at the time: Messenger on guitar; Rick Shlosser on drums; Bill Church on bass; Mark Naftalin on piano and Jack Schroer on saxophone.

[4] Writer Peter Wrench commented that "What does seem clear, though, is that ‘Jackie Wilson’ is a genuine example of a one-take wonder which came together extraordinarily quickly as a shared creation in the moment.

[11] Biographer John Collis writes that the "scat phrase kicking off the first track, 'Jackie Wilson Said', hotly pursued by a confident big band r'n'b arrangement, promises well.

[18] Thomas Ryan wrote in 1996 that the song was "denied its commercial destiny by never gaining entry to the upper echelons of the singles charts, a fact as unacceptable as it is inexplicable.

"[19] In reviewing the album for the BBC, James Young describes the song as "soulful and uplifting" and comments that "it's awash with lyrical hooks powered by his increasingly mellifluous voice, and backed with pumping horns and rhythm section.

"[20] Robert Christgau wrote in his review of Saint Dominic's Preview, "'Jackie Wilson said it was reet petite,' he shouts for openers, and soon has me believing that 'I'm in heaven when you smile' says as much about the temporal and the eternal as anything in Yeats.

[28] English pop band Dexys Midnight Runners first performed "Jackie Wilson Said (I'm in Heaven When You Smile)" live at the Old Vic Theatre, London in November 1981.

[35] It was originally intended that Van Morrison would contribute to the track, but instead he intoned comments for fans in a monologue as an album coda, which was eventually cut.

[38] Dexys Midnight Runners' version was included in "Bomb", a 1982 episode of the television series The Young Ones,[39] as well as the 2012 romantic comedy film The Five-Year Engagement, which featured a number of Van Morrison originals and covers in its soundtrack.

[40] It was famously performed on Top of the Pops in front of a picture of Scottish darts player Jocky Wilson.

Head Automatica also released an acoustic cover of the song as part of the 2014 Fadeaway Records compilation Friends.
