"Johnny and Mary" was used as the signature tune in advertisements promoting Renault cars throughout the 1980s and 1990s. Early adverts used Palmer's original version, while a range of special recordings in different styles were produced during the 1990s, most famously an acoustic interpretation by Martin Taylor, which he released on his album Spirit of Django. Taylor recorded alternate versions for Renault; the last being in 1998 for the launch of the all-new Renault Clio. In 2021, Swedish singer Hanna Hägglund recorded a new version of the song, used again by Renault in TV ads to launch its latest version of model Clio.[10][11]

In 1989, model Leigh Jaeger released a version of the song as a single through A&M Records. Jaeger previously appeared as one of the models in the music videos for Palmer's "I Didn't Mean to Turn You On" and "Simply Irresistible". Jaeger's version was produced by Stephen Stewart-Short and the 12-inch format included a remix by Phil Harding and Ian Curnow.[26] The music video features vogue dancing and was the earliest to showcase the dance in the UK.[27]
