Written and first recorded (as a demo) by Barry Gibb (1982, released 2006).
Hit version by Dionne Warwick (US #10/R&B #14/MOR #1/UK #2/CAN #15/AUS #2 1982).
From the wiki: “‘Heartbreaker’ was written by Barry Gibb for Dionne Warwick, for her album Heartbreaker released in 1982. Gibb’s demo recording was not released until 2006.
“The song blended the two Gibb brothers schools of songwriting: it has the clear verse and chorus structure favored by Robin and Maurice, yet also has the longer spun-out verses Barry now preferred, both well balanced, so that it has instant appeal but takes repeated listenings to fully appreciate. Maurice said later that he wished they had saved it for themselves.
“Warwick admitted in The Billboard Book of Number One Adult Contemporary Hits, by Wesley Hyatt, that she was not fond of ‘Heartbreaker’ (regarding the song’s international popularity, she quipped, ‘I cried all the way to the bank’), but recorded it because she trusted the Bee Gees’ judgment that it would be a hit. It turned out to be Dionne’s most successful solo hit of the 1980s.”
