"That's All" is a song by English rock band Genesis. It is a group composition and appears as the second track on their 1983 album Genesis. It was the album's second single after "Mama". On June 17, 1993, MCA Records re-issued and re-released the song as a CD and "HiQ" cassette single. The U.S. single reached No. 6 in early 1984, making it their first Billboard Hot 100 Top 10 hit; it included "Second Home by the Sea" as the B-side. The UK single featured "Taking It All Too Hard" as the flipside, and reached No. 16. Also released was a 12-inch single that included a live version of "Firth of Fifth" from 1981. As the band's first break into the Billboard Hot 100 Top 10, the song is included in Rock Song Index: The 7500 Most Important Songs for the Rock and Roll Era.[1]
