LED ZEPPELIN At Knebworth (1979 UK 28-page programme for the concerts held at Knebworth House on the 4th and 11th of August 1979, with photographs and biographies of all the artists featured on the bill including Fairport Convention, Todd Rundgren And Utopia, Southside Johnny and Chas And Dave. This cover shows a degree of creasing commensurate with its age but has also been nicely AUTOGRAPHED inside by Robert Plant 'To Maria, Happy Days' over his portrait picture. The signature was obtained when Maria's sister, who sings with the London Orianna Choir and sang at the 2010 BBC Electric Proms with Robert Plant, sang with Robert again on 'My Sweet Lord' at Abbey Road studios to celebrate George Harrison's birthday. This is where she took the opportunity to speak to him and get the programme signed. When he looked at the programme he seemed most surprised and said 'You have kept this all this time?' and then went on to say that it brought back many happy memories hence the 'Happy days' above his signature. Like all autographed items, a one off, but this has quite charming provenance to go with it as well)
