"Breaking Up Is Hard to Do" is a song recorded by Neil Sedaka, co-written by Sedaka and Howard Greenfield. Sedaka recorded this song twice, in 1962 and 1975, in two significantly different arrangements, and it is considered to be his signature song. Between 1970 and 1975, it was a top-40 hit three separate times for three separate artists: Lenny Welch, The Partridge Family and Sedaka's second version. Original version In his daily mini-concert on June 12, 2020, Sedaka recalled that the song's iconic scat intro was a result of him and Greenfield being unable to come up with a lyric for that section of the song and Sedaka improvising a vocalise, which they liked so much that they kept it in the finished product. Described by AllMusic as "two minutes and sixteen seconds of pure pop magic," "Breaking Up Is Hard to Do" hit number one on the Billboard Hot 100 on August 11, 1962, and peaked at number twelve on the Hot R&B Sides chart. The single was a solid hit all over the world, reaching number 7 in the UK, sometimes with the text translated into foreign languages. For example, the Italian version was called "Tu non lo sai" ("You Don't Know") and was recorded by Sedaka himself. On this version, background vocals on the song are performed by the female group The Cookies. The personnel on the original recording session included: Al Casamenti, Art Ryerson, and Charles Macy on guitar; Ernie Hayes on piano; George Duvivier on bass; Gary Chester on drums; Artie Kaplan on saxophone; George Devens and Phil Kraus on percussion; Seymour Barab and Morris Stonzek on cellos; and David Gulliet, Joseph H. Haber, Harry Kohon, David Sackson, and Louis Stone on violins. Chart history Weekly charts Year-end charts Lenny Welch version Though it was originally an uptempo song, Lenny Welch re-recorded the song, reimagined as a torch ballad. Welch had approached Sedaka to see if he had any songs in his repertoire that fit Welch's style; as most of the songs Sedaka had written with his usual partner Howard Greenfield were upbeat pop songs, he did not, but playing around on the piano, he discovered "Breaking Up is Hard to Do" worked well as a slow ballad, so he wrote a new introduction and offered it to Welch. It peaked at #34 on the US Billboard charts and #8 on the easy listening chart
