I used clearance.com
which is the website for Evan M. Greenspan, INC. (a music clearance company)
For a small fee they provided me with the contact information for the owners of the synch rights to the music.
Then I contacted the owners and worked out a student rate... as that was one of my last student films, it was still elligible for a student rate.
After about four months... only the last two to three weeks of which I actually "WORKED" on getting my rights... the 1 year festival license was secured.
So, yes... I do own the rights to use "Bang Bang" in "THE DUEL" for the course of 1 year's time... through the end of next september. It did cost me... but not as bad as many would think.
If you wish to get more detailed information... please e-mail me... my e-mail address is provided in my profile.
If I get enough mail about this... I will just create a thread in a forum...
but for now, I will answer everyone's e-mail individually (or in groups).
Happy clearing!
