"A Thing Called Love" is a song written and originally recorded by Jerry Reed in 1968. This song has been recorded by many artists, including Jimmy Dean, Elvis Presley, Glen Campbell, and Lynn Anderson. In 1971, the song was recorded by Johnny Cash and it became a No. 1 country hit in Canada.

The piece is usually performed at a fast tempo; the 1956 recording of Clifford Brown and Max Roach with Sonny Rollins is one of the best-known uptempo instrumental versions.

Britain's “Radio Sweetheart Number One,” singer Elsie Carlisle, introduced “What Is This Thing Called Love?” to the London Pavilion on March 27^th, 1929. The song was performed as part of Wake Up and Dream, a musical revue with words and music composed by Cole Porter and the book by John Hastings Turner.
