"Let My Love Open the Door" was released as the second single from "Empty Glass" in Britain, where it was backed with the non-album tracks "Classified" and "Greyhound Girl." The song was a minor British hit, reaching number 46. The song saw more success when it was released as the debut single from "Empty Glass" in America, where the song reached number nine. It was Pete Townshend's only solo top 10 hit on the "Billboard" Hot 100, but The Who's song "I Can See for Miles," which was written by Townshend, reached the same position on the chart 13 years earlier.
