I don't know if this has been posted before or not, but www.crimelibrary.com has an expose story on Sweeney Todd. It delves into the true story behind the myth and uses a lot of quotes and pictures from the musical. There is also a "chapter" dedicated to the Broadway show. If you are a fan of Sweeney and have some time to spare, it is an interesting read.
"You pile up enough tomorrows, and you'll find you are left with nothing but a lot of empty yesterdays. I don't know about you, but I'd like to make today worth remembering." --Harold Hill from The Music Man

That is a very interesting article. There is a book on the subject as well, "Sweeney Todd:The Real Story of the Demon Barber of Fleet Street" by Peter Haining. It's basically a more in depth version of the crime library article. But both of those were written with the belief that Todd and Lovett were real people, while others maintain that he was created from a combination of other people and legends. In his introduction to the libretto, Christopher Bond, who wrote the play before it was a musical, states that Todd is absolutely fictional. It's hard to know what to believe-some of Haining's conclusions in his book seemed a little bit far fetched.
