As Sandy Troy, via deadessays, Garcia was persuaded to do a 30-second Levi's radio commercial.
Not sure where the name "Set Me Free" came from, but this is song based on Blue Yodel #9. Lyrics are changed to stuff like "A good pair of Levi’s are bound to set me free"and "Levi’s 501 jeans shrink to fit only me."
