"Miss You in a Heartbeat" is a song by English hard rock band Def Leppard, released in December 1993 by Mercury Records from their 1993 compilation album Retro Active. The single peaked at number 39 on the US Billboard Hot 100 and was Def Leppard's last American top 40 single to date.
Background
Three versions of the song appear on Retro Active; the acoustic version (4:04), which was released as the single, the electric version (4:56), which was one of the bonus tracks for the Japanese pressing of Adrenalize along with "She's Too Tough", before both were remixed for Retro Active, and the piano version which is featured as a hidden track on the Retro Active album. It is played after the electric version of "Two Steps Behind".
Although "Miss You in a Heartbeat" was written by Def Leppard guitarist Phil Collen, it was initially recorded and released by The Law on their 1991 self-titled debut.[2]
