It was later recorded by John Stamos in his role as Gino Minelli, on the original soundtrack of the CBS sitcom Dreams in 1984. American rock band Heart made it a number one US and Canadian hit in 1987. Twenty years later, Céline Dion recorded it for her album Taking Chances.
The song was given to Heart and released as the first single from their ninth studio album Bad Animals in May 1987. Heart's version is a power ballad that begins with a piano line and a subdued vocal from Ann Wilson, and builds to a dramatic power ballad.
According to a Songfacts interview with Steinberg, Kelly (an experienced session singer) provided the high harmony parts on the record. "Alone" is Heart's biggest hit, spending three weeks at number 1 on the U.S. Billboard Hot 100 that July. It ranked number 2 on the Billboard Year-End Top Pop Singles of 1987. It is also their most successful single in the United Kingdom, where it peaked at number 3 on the UK Singles Chart.The song's popular video featured the band in a synched live performance. An "unplugged" version of the song later appeared on Heart's 1995 album The Road Home.
