"I'm Sorry" is a song written and recorded by American country-folk singer-songwriter #JohnDenver and released in 1975. It was the final number-one pop hit released during his career. The flip side of "I'm Sorry" was "#Calypso", and, like its A-side, enjoyed substantial radio airplay on #Top40 stations. "I'm Sorry" is an apology for forsaken love. In the lyrics, the singer's love interest has left him and he's still broken up about it weeks later.
