oops I made a typo above - 50th instead of 60th.

the wikipedia police removed a pic of descendants of one of the Bush Music club's early members signing a copy of his biography!! Pic of the book was posted with the permission of his granddaughter who is his literary executor ...

I just checked wikipedia & found this under Features -
For the 5 days of the festival, there is also an almost continuous Session in the world-famous "Session Bar", known as the 'London Underground' of folk music, that only stops briefly due to alcohol licence restrictions in the early morning and kicks off again in mid morning for another round the clock session of music and culture.

London Underground???

Details of the festival are a tad old - Bush camp, Balls,etc - & the latest revision was 22 May
