[source: NME.com] Led Zeppelin's former guitarist Jimmy Page will testify against a bootlegger in Scotland. Robert Langley was arrested in Glasgow in 2005 with what police claimed was more than AU$50,000 worth of pirated CDs. Among these were Led Zeppelin shows that have never been released, including one at Knebworth from August 1979. Other items included unreleased material from The Beatles and Bob Dylan. Page has already been to Glasgow to identify the Led Zeppelin tapes for investigators from the British Phonographic Institute. The guitarist will reportedly testify when the trial is held in the city's Sheriff Court.
