"Sure Know Something" is a single by American hard rock band Kiss, released on their 1979 album Dynasty.
Written by vocalist/guitarist Paul Stanley and producer Vini Poncia, "Sure Know Something" reached number 47 on the U.S. Billboard Hot 100 singles chart in 1979, and in the Top Ten in some countries around the world.[2] It would become another top ten hit (number 5) for the band in Australia.
Cash Box said the song "has a rock-anthemic quality" and praised the hook.[3]Record World called it a "megarocker that bowls you over with sheer power and enthusiasm."[4]
A promotional video, directed by John Goodhue, was filmed for the single and featured the band on a mock-up of what was their Dynasty-era stage show.[5] "Sure Know Something" was performed by the band acoustically during their MTV Unplugged performance in 1995 and with the Melbourne Symphony Ensemble on their live album Kiss Symphony: Alive IV.
The song incorporates disco music into the usual style of a rock ballad. It is one of two disco rock hits for the band, the other being "I Was Made for Lovin' You". It is seen as being one of the more sophisticated songs written by Stanley, with critics noting the heartfelt feelings of confusion and sorrow. The song musically and lyrically is darker than most Kiss songs, with the song being played in a minor key and the lyrics referring to being overwhelmed by loss of virginity.
