"Love's Old Sweet Song" is a Victorian parlour song published in 1884 by composer James Lynam Molloy and lyricist G. Clifton Bingham. The first line of the chorus is "Just a song at twilight", and its title is sometimes misidentified as such. The song has been recorded by many artists, including John McCormack and Clara Butt. The song is alluded to in James Joyce's Ulysses as being sung by Molly Bloom. The song was recorded in 1923 for a two-reel short film made in the DeForest Phonofilm sound-on-film process. It also appeared as the theme in the orchestral score in John Barrymore's 1926 picture The Sea Beast.
1954 Bing Crosby recorded the song in 1956 for use on his radio show and it was subsequently included in a CD On the Sentimental Side issued by Collectors' Choice Music in 2010. Crosby also included the song in a medley on his album 101 Gang Songs

The track A losing battle is raging, from The Caretaker's 2017 album Everywhere at the end of time , features an instrumental sample of the song taken from a 78 rpm record, looped and manipulated in a deliberately disorientating fashion to reflect the fictional protagonist's steadily worsening dementia.
