Some rock legends are taking a music memorabilia Web site owner to court, claiming he is illegally selling vintage recordings and other items.

The plaintiffs — Grateful Dead Productions, Carlos Santana and members of Led Zeppelin and The Doors — filed a federal lawsuit Monday against William Sagan, operator of Wolfgang’s Vault. The San Francisco-based Web site sells material Sagan obtained after purchasing some of the assets of Bill Graham, the famed concert promoter who died in a 1991 helicopter crash.
