How do infringement cases affect the $15bn global music industry?
Led Zeppelin have appeared in court to fight against a lawsuit claiming they borrowed from another song without credit or payment. Guitarist Jimmy Page and singer Robert Plant are expected to give evidence in Los Angeles regarding their 1971 hit 'Stairway To Heaven'. The band is being sued by owners of a trust acting for Randy Wolfe, lead guitarist of the band Spirit, who died in 1997. Matt Cox has been finding out what the lawsuit is all about by speaking with Elliot Chalmers, of Independent Music Law Advice.
