How Long (will it take) was first discussed back in 2007 when an alternate pitch version of it was discovered, uncredited, on many russian bootleg DVDs. After a 16 year long search, it was finally correctly credited to indie artist Paula Toledo, who had sung it for a gig in Toronto, Canada, and was approached by a Lionsgate employee who wished to license it for a film. Pretty soon, it spread all over the world and ended up on the bootleg discs. Paula's music is very wonderful, so please give it a listen if you have the time!
