In 2008, Purdy recorded three new songs, a cover version of a Southern gospel classic and two re-recorded new versions of the songs from his album "Art of Love", to be included in the soundtrack of English Director Thomas Clay's film "Soi Cowboy". The three new tracks included the theme song "Where We'll Never Grow Old" ("Never Grow Old"), an uptempo version of "Yaak Euie Wa Ruk" () and a live-like recording of "Yar Ton Eak Leoy" (). At the 61st Cannes film festival, "Soi Cowboy" was selected for Un Certain Regard Award consideration, and for his effort on the soundtrack, Purdy received the same honor in the music category.
