The Beatles' Beloved Cavern Club Sues Hard Rock Cafe

England’s Cavern Club, the Liverpool nightclub revered by fans of the Beatles for launching the Fab Four in their homeland, slapped the Hard Rock Café International with a lawsuit Sunday in Las Vegas alleging trademark infringement.

The Cavern Club, which calls itself the "cradle of British pop music," still features Beatles tributes and other performers.

Now, the famed club is taking issue with an events room called "The Cavern Club" at one of the Hard Rock's Las Vegas cafe locations. Hard Rock Cafe International, owned by Florida’s Seminole Indian tribe, does not own the Hard Rock Hotel casino in Las Vegas and is involved in a trademark lawsuit with the hotel-casino.
