Pirelli's Miracle Elixir is the seventh song in the movie. It's sung by Toby, Sweeney and Mrs. Lovett.
During the song, Sweeney and Mrs. Lovett head to St. Dunstan's market, where Tobias Ragg is selling the "Miracle Elixir" of one Adolfo Pirelli. The two soon learn that the elixir in question is nothing but a concoction of urine and ink, and nothing but a fraud meant to separate people from their money, and waste no time in spreading this word to everyone at the market, disrupting Toby's sales pitch in the process. This serves to draw out Adolfo Pirelli himself, leading into The Contest, where Sweeney challenges Pirelli.
Toby: Ladies and gentlemen! May I have your attention, perlease? Do you wake every morning in shame and despair To discover your pillow is covered with hair Wot ought not to be there? Well, ladies and gentlemen From now on you can waken at ease You need never again have a worry or care I will show you a miracle marvelous rare Gentlemen, you are about to see Something wot rose from the dead-- On the top of my head!
