For anybody who has wondered exactly what the second touch function on a theatre organ actually does or how it is used? , Here is an informative U-Tube link of Nigel Ogden at the Blackpool Tower.
It also demonstrates the famous Blackpool Mutation couplers on the Solo Manual (you either love or hate these). Being a Theatre Organ fan- I like them- but only when used sparingly.
