I went to the David Bowie exhibition at the Royal Festival Hall (downstairs) for a fiver the other day. I found it incredibly informative and interesting, and being somewhat of that age, it took me back, with a really good warm glow feeling.
Lots of information there which I was unaware of in the making of the album, along with the Hasselblad large format camera used for shooting the iconic cover.
Then there is the bench or bean bag room playing the music through on a loop.
Overall great stuff, and well worth the £5 entry fee.
I fully recommend it.
