Bert Jansch is a name unknown to most Rock fans, but a number of super stars credit the late founding member of the band Pentangle as one of their big influences. Jansch died two years ago of lung cncer. On Tuesday (12/3), a tribute concert arranged in his honor on what would have been his 70th birthday featured performances and accolades from Robert Plant, Donovan and Pentangle members Jacqui McShee, Danny Thompson and Terry Cox. Neil Young was unable to attend the Royal Festival Hall event in London, but sent a video of him performing the Jansch song Needle Of Death, which Young credits as having inspired The Needle & The Damage Done, the song Young penned after losing a band mate to heroin. Plant, who sang Go Your Own Way My Love in honor of Jansch, said, 'We all came to a similar place but we concentrated on different levels. Bert was a digger for all of us.'
