That's the place Grandarog - well done.
Many Kent bands have used Graveney Village Hall for rehearsals. In the 70s/80s I was often there taking promo photos and advising on PA gear (I had a music shop).
As far as I know the most famous bands that rehearsed there were Wilde Flowers, Soft Machine and Caravan. All part of the 'Canterbury Sound'. Caravan were regulars in my shop. The drummer, the late Richard Coughlan lived on the same estate as me and we went to primary school together. We were good mates until the last day of Primary school. We fell out over something trivial and ended up having a fight. Both walked into school on our last day covered in blood and were sent home. We went on to different secondary schools and lost touch for many years. Richard had two pubs. One in Ashford and more recently, The Cricketers in Canterbury. Richard had been unwell for some time and sadly passed in 2014. Geoff Richardson, the electric viola player and I spent many hours in the early days of home computers, learning BASIC programming. We had Commodore Pet computers then.
Hastings, Coughlan and the Sinclairs formed Caravan Mk I in 1968, landing a deal with MGM’s Verve Forecast imprint after Island’s Chris Blackwell turned them down. Already penniless they wrote songs while living in tents pitched outside Graveney Village Hall.
