I have uploaded a video I made of the Alan Ralphs Photograph Collection, which is in the care of George Houghton.
It shows the early days of preservation of fair organs and steam from the 1950s, but also shows some earlier pictures of fairground. Members of the preservation group(s), mainly the Fellowship Circle of Showland Friends (FCSF) are also shown.
The video runs for about 28 minutes, so in order to keep the file size as small as possible, I reduced the video to 320 x 240, but it is still a hefty 51 MByte file!
The music is from the "Amsterdam Memories" CD, which is also in George's care. It is only at a 'background music' volume!
