"Hourglass / Theme from Harry's Game" is a double A-side single by Irish musical group Clannad. It was released in 1989 to promote their best-of Past Present. This is the band's only single to feature a lead song that doesn't appear on any album, and the band's only double A-side single to date. Two promotional videos were produced to accompany the single, one for each of the lead songs, "Hourglass" directed by Tim Morris & Pól Brennan, and "Theme from Harry's Game" by Billy Magra.
