My sister and I today visited the Musical Museum near Kew Bridge in London. I'd seen it advertised in the "2 for 1" booklet for people travelling to London by train.
It was excellent and so interesting as the entry price (very reasonable) included an audio guide. We were able to see various automatic musical instruments including music boxes and pianolas. Some gigantic music-playing machines were coin-operated, the fore-runner of juke-boxes.
We had arranged to visit on a Tueday afternoon so that we could have a guided tour of the Museum and this was really good. We were able to listen to various of the instruments playing their music and have a close look at the old paper music rolls.
Upstairs we were shown into the concert hall and had a demonstration of the wonderful old Wurlitzer organ.
Ideal for adults – not really suitable for youngsters as not "hands-on like so many museums are now.
Shame the tea room wasn't open, but would certainly not have been worth as we were the only visitors present at the time!
