Quote: "I'm sure that Catherine Slack is correct. However, it has to be Shipley Glen as there wasn't a switchback or an aerial flight (aerial slide) at Shibden Dale"

It is interesting to note that Shibden Valley runs downhill from Catherine Slack. Following the valley below Shibden Park we come to the long defunct Sunny Vale Gardens - about half a mile further downstream there was an aerial ropeway connecting Walterclough Coal & Clay mine with a road higher up on the Hipperholme side of the valley. It was certainly there in the 1940's and the remains can still be seen today.

Shipley Glen Railway wasn't an aerial flight, it was and is a cable hauled tramway, the cable of which runs close to the ground. The Walterclough ropeway probably ran upto 100 feet in the air.

Still what Shibden Glen and Catherine Slack had to do with Sowerby Bridge is beyond me.

I remember Sunday nights in the Eagle Tavern in Leeds in the 70/80's. A band, Aikens Drum, played there and they sang this song. I have a copy on a record, but nowadays no record player! Doh!
