"Telephone Line" is a song by English rock band Electric Light Orchestra (ELO).

[6] With ELO's continuing success in America it seemed obvious to frontman Jeff Lynne to use an American ring tone during the song.

[11] AllMusic's Bruce Eder said that "Telephone Line" "might be the best Lennon–McCartney collaboration that never was, lyrical and soaring in a way that manages to echo elements of Revolver and the Beatles without ever mimicking them.

"[12] Stereogum contributor Ryan Reed rated it as ELO's best song, calling it "a high watermark for harmony, humor, arrangement, production, engineering, and emotion.

[15] Cash Box said that "Jeff Lynne's voice verges on the choking sob, and the unearthy strings and "doobie-doo-wa's" should clinch top 40 ears.

[18] "Telephone Line" is the theme song of the 1977 film Joyride starring Desi Arnaz Jr., Robert Carradine, Melanie Griffith, and Anne Lockhart, directed by Joseph Ruben.

[36] In 2012, as part of the concert from his home studio, Live From Bungalow Palace, Lynne performed an acoustic version of the song with longtime ELO pianist Richard Tandy.
