"Good-bye-ee!" is a popular song written and composed by R. P. Weston and Bert Lee. Performed by music hall stars Florrie Forde, Daisy Wood, and Charles Whittle, it was a hit in 1917.
Weston and Lee got the idea for the song when they saw a group of factory girls calling out goodbye to soldiers marching to Victoria station. They were saying the word in the exaggerated way which had been popularised as a catchphrase by comedian Harry Tate. They then travelled to Brighton and wrote the song on a wet afternoon in their cabin under the pier.
The song lent its name to "Goodbyeee", the final episode of the sitcom Blackadder Goes Forth.
The salutations at the end of the chorus are from various languages. Bonsoir is French for goodnight. Chin chin is a Chinese toast. "Nahpoo" and "toodle-oo" are English idioms from corruptions of the French il n'y en a plus (there is no more) and ÃÂ tout ÃÂ l'heure (see you later).
