I doubt it. It's about being compensated for the use of your product. I'm not saying Janie is business genius but at least they're not door mats.
I'd have to guess that there was some offer made but it was refused. I mean, who would really make a Hendrix movie without at least trying to get the music.
I don't think the EH trust is too interested in preserving Jimi's legacy. It's a money grab. Remember, this is the same group that brought us Jimi Hendrix vodka.
