who wrote the song didn i blow your mind this time
Didn't I (Blow Your Mind This Time) "Didn't I (Blow Your Mind This Time)" is a song co-written by record producer Thom Bell and William Hart, lead singer of the American R&B/Soul vocal group The Delfonics. It was released by the group in 1969 on the Philly Groove record label and is regarded as a classic, winning a Grammy Award for Best R&B Performance by a Duo or Group. Considered one of the most notable early Philly soul singles and 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.
