Pete.
You've got all the best books on your list. There are a few others worth checking out:
Keeping The Faith - photography by John Barrett, a collection of black and white photos.
Groovesville USA by Keith Rylatt, the definitive Detroit book.
The Rare Soul Bible by Dave Rimmer, a reference work.
Manchester England by Dave Haslam, the history of the city's music with some Northern references.
Young Hearts Run Free by Dave Haslam, a story of the 1970's with some Northern references.
On The Right Track by Rob McKeever, Ginger's story.
Stuart Maconie's Cider With Roadies has a brilliant Chapter 6, "Out On The Floor" - this is worth the price of the book alone but it is a great book anyway.
Hope this helps.
