"I'm Sorry" is a R&B/Soul song by the American vocal group The Delfonics, released in April 1968. The song was the Delfonics' second chart single and the follow up to their smash hit La-La (Means I Love You), which went to #4 on the Billboard Hot 100; indeed, "I'm Sorry" was quite reminiscent of their earlier hit, complete with similar-sounding "la la las". "I'm Sorry" just missed the pop Top 40 (peaking at #42), but was a solid performer on the soul charts, hitting #15.

"I'm Sorry", and several other soul tunes, were unintentionally included in the background of Jim Jones' infamous Death tape, an audio recording made during the Jonestown Massacre of November 18, 1978. [1] The music (which sounds muffled and played at off-speed, resembling a church organ in spots) was originally recorded onto the source tape, then recorded over by Jones, resulting in a "ghost recording". "I'm Sorry" can be heard at the very end of the tape after Jones stops talking, played at half-speed. [2]
