In 2004, Henry Lytton Cobbold edited and designed Knebworth: 30 Years of The Greatest Rock Venue in The World!
A member of the family who have lived at Knebworth House for over five hundred years, Henry's compilation is an entertaining look at the concerts which have been held in the ground since 1974.
The book starts with a brief family history - taking the story from 1490, when the grounds were chosen for the construction of the house.
While ''Knebworth'' includes quite a few photographs and recollections as well as reprinted tickets and posters, Henry admitted not including much about one of the biggest names who played there. There's ''just a snapshot of Elton one of the concert screens,'' he says.
There is currently a related exhibit, running through the end of the month, which Henry says is more about the events than the artists.
''So there is Knebworth '90 memorabilia, but not specifically Elton memorabilia.''
''The book and the exhibit are a celebration of Knebworth as a venue - they are compiled using quotes, scrapbook memorabilia and posters and t-shirts.''
