I don't know if this kind of petition is legally binding:
A petition to see the release of a trio of professionally recorded soundboards from the Rolling Stones' November 1969 Madison Square Garden stand has nearly met its goal of 2,500 signatures. Two of the shows were briefly available online as a copyright protection drops before being yanked prior to the masses being able to download them.
In addition to tracks recorded from the band's November 26th, 1969 gig at the Baltimore Civic Center, the 1970 Get Yer Ya-Ya's Out: The Rolling Stones In Concert album was culled from the Stones' November 27th and 28th MSG performances. In 1970, there was extensive post-production added to the raw tapes by Mick Jagger and Keith Richards at London's Olympic Studios.
