An Innocent Man is the ninth studio album by Americansinger-songwriterBilly Joel, released on August 8, 1983. The concept album is a tribute to the American popular music of Joel's adolescent years with Joel paying homage to a number of different popular American musical styles from the late 1950s and early 1960s, most notably doo-wop and soul music. The album cover artwork was taken on the front steps of 142 Mercer Street, just north of the intersection of Mercer and Prince Street in the SoHo neighborhood in New York City.
The album featured three Billboard Top 10 hit singles: "Tell Her About It" (No. 1), "Uptown Girl" (No. 3) and "An Innocent Man" (No. 10). Four other singles were released from the album: "The Longest Time" (No. 14), "Leave a Tender Moment Alone" (No. 27), "Keeping the Faith" (No. 18) and "This Night" (US B-side of "Leave a Tender Moment Alone"). "Tell Her About It" and "Uptown Girl" garnered international success—"Uptown Girl" reached No. 1 in the UK, Australia and New Zealand. An Innocent Man remained on the US Pop album chart for 111 weeks, becoming Joel's longest charting studio album behind The Stranger. For over a year, the album remained on the charts in the UK, Japan and Australia.
In an interview about the making of the album, Joel talks about the fact that at the time that he was recording An Innocent Man, he was newly divorced from his first wife, Elizabeth Weber, and was single for the first time since achieving rock star status. So he had the opportunity to date supermodels like Elle Macpherson and Christie Brinkley, and because of these experiences, he said, "I kind of felt like a teenager all over again."  And so he started writing songs in the same style as pop songs that he remembered from his teenage years, citing pop music from the late 1950s and early 1960s, including "early R&B songs and The Four Seasons, and the Motown music, soul music."
Joel explained, "When you're gonna write [songs for a new album], you write what you're feeling. And I didn't fight it. The material was coming so easily and so quickly, and I was having so much fun doing it. I was kind of reliving my youth. ... I think within 6 weeks I had written most of the material on the album." Joel also said that he was pleasantly surprised to have hit records in the 1980s with retro songs like the mostly a cappella doo wop song "The Longest Time."
All songs by Billy Joel, except for the chorus for "This Night," which is credited on the sleeve to L. v. Beethoven.
The track listing on the LP is slightly different from that on the cassette and original CD pressings, with the latter swapping the places of "The Longest Time" and "Uptown Girl" respectively. However, on the actual cassette shell and disc label, the songs are listed (and play) in the correct order as printed on the LP.
