The Boy I Love is Up in the Gallery was a song written in 1885 by George Ware for Nelly Power; it was popularised by Marie Lloyd (1870-1922), another well-known star of the late 19th and early 20th Century Music Hall.
The boy I love is up in the gallery,
The boy I love is looking now at me,
There he is, can't you see, waving his handkerchief,
As merry as a robin that sings on a tree.
