Also, at the time of his death, Hartman's music was enjoying a revival of sorts: a cover version of "Relight My Fire" became a British number-one hit for Take That and Lulu in 1993. Sales of Hartman's solo recordings, group efforts, production, songwriting and compilation inclusions had exceeded 50 million records worldwide. Around December 1994, the album "Keep the Fire Burnin'" was posthumously released – a compilation featuring remixes of earlier hits and previously unreleased material. The album spawned two singles; "Keep the Fire Burnin'" – a duet featuring Holloway – and "The Love in Your Eyes". Hartman's version of "Free Ride" was featured in "" the year after his death. In 1996, Audio Adrenaline included a cover version of "Free Ride" on their album "Bloom".
