Sondheim explained how the song became a hit: "First of all, it wasn't a hit for two years. I mean, the first person to sing it was Bobby Short, who happened to see the show in Boston, and it was exactly his kind of song: He's a cabaret entertainer. And then my memory is that Judy Collins picked it up, but she recorded it in England; Sinatra heard it and recorded it. And between the two of them, they made it a hit." Frank

It is a ballad from Act Two, in which the character Desirée reflects on the ironies and disappointments of her life. Among other things, she looks back on an affair years earlier with the lawyer Fredrik, who was deeply in love with her, but whose marriage proposals she had rejected. Meeting him after so long, she realizes she is in love with him and finally ready to marry him, but now it is he who rejects her: He is in an unconsummated marriage with a much younger woman.

The sense is rather of jesters and fools, as Sondheim explained in a 1990 interview: "I get a lot of letters over the years asking what the title means and what the song's about; I never thought it would be in any way esoteric. I wanted to use theatrical imagery in the song, because she's an actress, but it's not supposed to be a circus [...] [I]t's a theater reference meaning 'if the show isn't going well, let's send in the clowns'; in other words, 'let's do the jokes.'

In a 2008 interview, Sondheim further clarified: "As I think of it now, the song could have been called 'Send in the Fools'. I knew I was writing a song in which Desirée is saying, 'aren't we foolish' or 'aren't we fools?' Well, a synonym for fools is clowns, but 'Send in the Fools' doesn't have the same ring to it."

Content:  The lyrics of the song are written in four verses and a bridge and sung by Desirée. As Sondheim explains, Desirée experiences both deep regret and furious anger: "'Send in the Clowns' was never meant to be a soaring ballad; it's a song of regret. And it's a song of a lady who is too upset and too angry to speak – meaning to sing for a very long time. She is furious, but she doesn't want to make a scene in front of Fredrik because she recognizes that his obsession with his 18 year-old wife is unbreakable. So she gives up; so it's a song of regret and anger, and therefore fits in with short-breathed phrases."
