It is performed by Dinah the Dining Car, after being dumped by her macho boyfriend, Greaseball.
The song starts with Dinah describing to her friends that "I've been..." before confessing that she "can't say the word."
Andrew Lloyd Webber wrote the song in the key of B flat major.
The song is reprised when Greaseball can't find the word to apologise to Dinah.
