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. Philly Groove Records - LP 1150
