Didn't I (Blow Your Mind This Time)

"Didn't I (Blow Your Mind This Time)" is a 1970 single by The Delfonics, produced by Thom Bell and released on the Bell record label. The recording is considered one of the most notable early Philly soul singles to be released and is regarded as a classic, winning a Grammy Award for Best R&B Performance by a Duo or Group. Typical of the genre, "Didn't I" is a slow love ballad, with layered strings, horns, and chromatic production. Among The Delfonics' signature songs, "Didn't I (Blow Your Mind This Time)" was a #3 hit on the Billboard R&B singles chart, #10 on the Billboard pop chart in 1970, and #22 on the UK Singles Chart in 1971.

The song has been extensively covered since 1970, with versions by Aretha Franklin (from "Young, Gifted and Black" in 1971), brothers David and Jimmy Ruffin, Regina Belle, Jackie Jackson, Millie Jackson, The Trammps, Maxine Nightingale and Patti LaBelle. The song was also featured as a song that actually drives the plot in the motion picture Jackie Brown (Max hears the LP vinyl version for the first time at Jackie's house and they talk about the Delfonics as he gets to know her, then later he buys the cassette version) and was included in its soundtrack.
