Did you know that the first theme restaurant in this chain was founded in 1971, by two Americans in London? The cafe begun covering its walls with rock & roll memorabilia eight years later, once Eric Clapton donated an un-signed red Fender Lead II to Hard Rock Cafe London, where he was a regular customer. HRC has now not less than 175 locations in 53 countries. Their collection of rock & roll memorabilia comes part from donations and some are purchased at auctions around the world.
